What the numbers are, where they come from, and where the public data runs out.
Every figure on Edgework is pulled live from NHL’s public web API at api-web.nhle.com. The homepage leaderboards draw on the NHL EDGE tracking feed — the same puck-and-player tracking that powers broadcast graphics — while player profiles blend EDGE data with classic box-score stats.
The six leaderboard cards each call a dedicated EDGE “top-10” endpoint — skating speed, speed bursts, skating distance, shot speed, offensive-zone time and 5-on-5 save percentage. The six endpoints are fetched in parallel and normalized into one shape so the page can render them identically. Speed Bursts · 20+ MPH sums the 20–22 mph and 22 mph-plus tracking buckets for a true count at or above 20 mph.
Top Forwards and Top Defensemen rank by points, split out of the league-wide scoring list. Top Goalies ranks by wins: goals saved above expected(GSAx) is the metric we’d prefer, but it requires an expected-goals model that NHL does not publish through the public API.
NHL does not expose public top-10 leaderboards for shots on goal or high-danger shots — that tracking data lives only on individual player pages. As a result those two leaderboards are not shown here. Anything we cannot source cleanly is left out rather than estimated.
Leaderboard data is cached for one hour; player profiles are cached for twelve. The “last refreshed” timestamp in the footer marks when the homepage last regenerated.
