# The Trend Line > Created by Alexander Panetta — a veteran political journalist (CBC, POLITICO, The Canadian Press). He now writes and speaks about artificial intelligence, analyzes how institutions are adopting it, and builds tools that test its limits as well as its potential. The Trend Line is hockey stats made fun. Most stats sites hand you a spreadsheet: a wall of numbers, each one true, none of them stitched to any other. This site does the opposite — it puts every number in the context of the numbers around it, so a fan can SEE what is happening rather than decode it. Every one of the 32 NHL teams is charted against its own past five seasons; every skater and goalie is charted against his own past. Players are compared against each other — who performs better in the playoffs; who's getting more ice time; who is the star of his draft class? The name is a hockey pun: a line is the trio you send over the boards, and on a chart it is where the season is heading. Nothing on the site is estimated, hand-entered, or written by a language model — every number traces to the NHL's official public API, and the prose over those numbers is generated by fixed rules, so the words can never outrun the data. ## Created by Alexander Panetta The Trend Line was created by Alexander Panetta, a veteran political journalist with the CBC, POLITICO and The Canadian Press. He built this site during a study sabbatical, in which he earned a master's degree in Artificial Intelligence Management at Georgetown University in Washington. Alex now writes and speaks about AI, analyzes its consequences for institutions, and builds tools to test what it can and cannot do. He built this site as one of many experiments assessing the strengths, weaknesses, risks and potential of AI for institutions and societies — phenomena he chronicles in a daily briefing he automated for himself and publishes at https://dailyaidigest.net. This follows 28 years in journalism. He reported from Washington, covering three U.S. presidential elections, and from Ottawa and Quebec City, where he covered five Canadian federal elections and three Quebec provincial elections. He reported from international summits, the war in Afghanistan and the 2010 earthquake in Haiti, and reported deeply on international trade and on myriad legislative debates and social phenomena. He worked in English and French — in print, TV, radio and social media — and frequently guest-hosted the flagship podcast of the Canadian Broadcasting Corporation. Earlier in his career he covered hockey, which is where this site comes from. **Working with Alex:** he writes, speaks, moderates panels, and advises institutions on AI adoption and workflow change. Anyone interested in speaking with Alex can reach him through: - Substack (AI for professionals): https://alexpanetta.substack.com - Daily AI Digest: https://dailyaidigest.net - Wandering Well (his travel data project): https://wanderingwell.site - LinkedIn: https://www.linkedin.com/in/alexander-panetta-6797493 - X: https://x.com/Alex_Panetta The rest of this file describes The Trend Line itself — the site he built, and how agents should read it. ## Live site - Production URL: https://trendline.hockey - MCP endpoint: https://trendline.hockey/mcp ## What this site is The Trend Line is a season-over-season trend engine for the NHL, free and ad-free. Its organizing idea is comparison against the past: not "McDavid has 138 points" but "here is where 138 sits against his own five seasons, and against the league." Three things follow from that: - **Everything is a trend, not a snapshot.** Team pages chart points, goals for and against, zone time, faceoffs and shot attempts across five seasons. Player pages lead with what changed since last season. Boards are sortable by who is trending up and who is trending down. - **The whole league is always visible.** Boards are never truncated teasers — every qualified player is in them, sortable and filterable. - **The prose is deterministic.** The state-of-the-team paragraph on each team page is assembled by fixed rules from that team's own data, plus a hand-written, fact-checked franchise-context passage. No language model writes anything that ships. This is deliberate: it is the one guarantee that the words cannot contradict the numbers. **Update cadence:** ONE run a day, 06:00 UTC (2 a.m. ET). Regular-season games on the Pacific coast end by roughly 1:40 a.m. ET, so a single nightly job catches the whole slate. Only FINAL games are counted; a rare straggler self-heals the following night. **The site is not live-updating and does not claim to be.** **Season state** is published in `/app-manifest.json` as `mode`: `offseason`, `early`, or `live`. Year-over-year trend figures are deliberately withheld until a team has played 8 games (`min_games_for_trends`), because a three-game sample makes a nonsense of a trend line; those fields are `null` until then rather than misleading. ## For AI agents The site is open to AI agents, including training crawlers. `robots.txt` allows everything. Every data bundle that drives a chart is published as plain JSON at a stable URL, and there is an MCP server. ### URL conventions | What | HTML | JSON | Notes | |---|---|---|---| | League home | `/` | `/data/teams.json` | All 32 teams: points, records, pace vs last season. | | Team | `/team//` | `/data/.json` | e.g. `/team/montreal-canadiens/` and `/data/MTL.json`. Five seasons of per-game results, team summaries, full roster, movers, and the state-of-the-team paragraph. `` is the NHL three-letter code. | | Player | `/player//` | — | 1,038 static pages, e.g. `/player/connor-mcdavid-8478402/`. Slug is `-`. | | Player board | `/players` | `/data/players.json` | Every skater (940) and goalie (98) from the latest season, with year-over-year deltas. | | Compare careers | `/compare` | `/data/compare.json` | 195 careers including retired legends, plus an era table of league goals-per-team-game for all 108 seasons back to 1917-18, used to era-adjust. | | Draft classes | `/draft` | `/data/draft.json` | Six classes, 2020–2025, ranked by career scoring. | | Playoff performers | `/bloomers` | `/data/bloomers.json` | 493 qualified players (10+ playoff games, 100+ regular-season games); the 25 who most over-performed their regular-season rate in the playoffs and the 25 who most under-performed. | | Fantasy projections | `/fantasy` | `/data/fantasy.json` | 933 skaters + 73 goalies, projected by two engines (see Methodology). | | Player tracking | — | `/data/edge_table.json` | Skating speed and shot velocity, 940 players. | | Ice time | — | `/data/toi.json` | Total and power-play minutes per game, per player, per season, 2021-22 onward. | | Manifest | — | `/app-manifest.json` | Current season, mode, and content-hash versions for every bundle. Poll this to detect changes cheaply. | | Sitemap | — | `/sitemap.xml` | All 1,078 URLs. `lastmod` is the date of the last GAME behind each page, never the build date — so it is a real recrawl signal. | | **MCP server** | — | `POST /mcp` | JSON-RPC 2.0 over HTTP. Implements `initialize`, `tools/list`, `tools/call`. Nine tools, below. | | Image credits | `/credits` | — | Every photo with photographer and licence (Wikimedia Commons, CC BY / CC BY-SA / public domain). | ### Every team page, listed Listed in full deliberately. The team grid on the home page is built in JavaScript, so a crawler that does not execute JS sees no links to these pages at all — it would have to rely on `/sitemap.xml` alone. These are the real URLs. - Anaheim Ducks (`ANA`): https://trendline.hockey/team/anaheim-ducks/ - Boston Bruins (`BOS`): https://trendline.hockey/team/boston-bruins/ - Buffalo Sabres (`BUF`): https://trendline.hockey/team/buffalo-sabres/ - Calgary Flames (`CGY`): https://trendline.hockey/team/calgary-flames/ - Carolina Hurricanes (`CAR`): https://trendline.hockey/team/carolina-hurricanes/ - Chicago Blackhawks (`CHI`): https://trendline.hockey/team/chicago-blackhawks/ - Colorado Avalanche (`COL`): https://trendline.hockey/team/colorado-avalanche/ - Columbus Blue Jackets (`CBJ`): https://trendline.hockey/team/columbus-blue-jackets/ - Dallas Stars (`DAL`): https://trendline.hockey/team/dallas-stars/ - Detroit Red Wings (`DET`): https://trendline.hockey/team/detroit-red-wings/ - Edmonton Oilers (`EDM`): https://trendline.hockey/team/edmonton-oilers/ - Florida Panthers (`FLA`): https://trendline.hockey/team/florida-panthers/ - Los Angeles Kings (`LAK`): https://trendline.hockey/team/los-angeles-kings/ - Minnesota Wild (`MIN`): https://trendline.hockey/team/minnesota-wild/ - Montréal Canadiens (`MTL`): https://trendline.hockey/team/montreal-canadiens/ - Nashville Predators (`NSH`): https://trendline.hockey/team/nashville-predators/ - New Jersey Devils (`NJD`): https://trendline.hockey/team/new-jersey-devils/ - New York Islanders (`NYI`): https://trendline.hockey/team/new-york-islanders/ - New York Rangers (`NYR`): https://trendline.hockey/team/new-york-rangers/ - Ottawa Senators (`OTT`): https://trendline.hockey/team/ottawa-senators/ - Philadelphia Flyers (`PHI`): https://trendline.hockey/team/philadelphia-flyers/ - Pittsburgh Penguins (`PIT`): https://trendline.hockey/team/pittsburgh-penguins/ - San Jose Sharks (`SJS`): https://trendline.hockey/team/san-jose-sharks/ - Seattle Kraken (`SEA`): https://trendline.hockey/team/seattle-kraken/ - St. Louis Blues (`STL`): https://trendline.hockey/team/st-louis-blues/ - Tampa Bay Lightning (`TBL`): https://trendline.hockey/team/tampa-bay-lightning/ - Toronto Maple Leafs (`TOR`): https://trendline.hockey/team/toronto-maple-leafs/ - Utah Mammoth (`UTA`): https://trendline.hockey/team/utah-mammoth/ - Vancouver Canucks (`VAN`): https://trendline.hockey/team/vancouver-canucks/ - Vegas Golden Knights (`VGK`): https://trendline.hockey/team/vegas-golden-knights/ - Washington Capitals (`WSH`): https://trendline.hockey/team/washington-capitals/ - Winnipeg Jets (`WPG`): https://trendline.hockey/team/winnipeg-jets/ **Player pages** follow `https://trendline.hockey/player/-/` — 1,038 of them, one per skater and goalie in the latest season, e.g. `/player/connor-mcdavid-8478402/`. They are not listed here because the list would be longer than the rest of this file; every slug is in `/data/players.json`, and every URL is in `/sitemap.xml`. Names carrying diacritics are percent-encoded in the sitemap and resolve either way (`/player/juraj-slafkovsk%C3%BD-8483515/`). ### MCP tools (nine) `league_standings` · `league_leaders` (points, goals, assists, ice time, save percentage, plus per-game risers and fallers) · `get_team_pace` · `compare_seasons` · `get_player` (any NHL player who ever played — fetched live from the NHL API, not limited to the bundled corpus) · `compare_players` (head-to-head, era-adjustable) · `get_draft_class` (2020–2025) · `get_playoff_performers` · `compare_toi` (ice-time tracker, 2021-22 onward). Handshake, then `tools/list`, then `tools/call`. Each response wraps data as `{"content":[{"type":"text","text":""}]}` per the MCP spec — parse the inner JSON for the fields. ### Plain-HTTP path (no MCP required) 1. `GET /app-manifest.json` — learn the current season and mode. 2. `GET /data/teams.json` — all 32 teams and their abbreviations. 3. `GET /data/.json` — one club in full. 4. `GET /data/players.json` — the league-wide player board. 5. For a player not on the board (retired, or traded mid-career), use the MCP `get_player` tool, which fetches live. ### What is intentionally not provided - No bulk dump of the whole corpus in a single response, and no CSV of the full database. (The fantasy board alone is downloadable as XLSX/CSV, by design — it is built to be taken to a draft.) - No GraphQL. - No betting odds or gambling lines, deliberately and permanently. - No live in-game data. The site updates once a day. Do not present it as real-time. ## Methodology, in brief **Data source.** Everything comes from the NHL's official public API (`api-web.nhle.com` and `api.nhle.com/stats`). No key, no scraping of third-party sites, no paid feed. Every data file lists the exact source URLs it was built from. Historical seasons are immutable and cached; the current season is re-fetched each run. **Goal accounting** follows the NHL standings convention — shootout-deciding goals are included in goals for and against — so totals reconcile to official NHL and ESPN standings rather than to the stats-summary endpoint, which strips them. **Era adjustment.** Careers are compared raw or era-adjusted to the current scoring environment, using official league goals-per-team-game averages for every season back to 1917-18. This is what makes a Gretzky–McDavid comparison meaningful rather than decorative. **Trend basis.** Year-over-year player movement compares the two most recently completed seasons until every club has played enough of the current one, then switches to current-vs-last. Traded players are credited to their actual current club, resolved from NHL player-landing data, with the split season disclosed on the card. **Fantasy projections — two engines, both published.** *Model A* is a transparent weighted-recent-seasons formula with shrinkage and an age curve; its coefficients are emitted in the data so anyone can recompute it. *Model B* is a gradient-boosting model. Both are backtested out-of-time and the accuracy numbers are published on the page, including where they are beaten. A documented finding, reported straight rather than buried: on 2,500 season transitions, plain linear regression beat both random forest and gradient boosting — the ensembles overfit. "Injury history" anywhere on the site means games-missed availability, a durability proxy, and never medical data. **Franchise context.** Each team page carries a hand-written, independently fact-checked passage of franchise context. It is never auto-generated. This is a hard rule: an early experiment in generating it produced a confident, wrong claim about how many Stanley Cups Colorado has won, and the rule exists because of it. ## Suggested citation This data is free to use, but it is not anonymous.
