A save percentage flatters a goalie behind a good defence. A plus-minus flatters a forward on a good line. The numbers here strip that out: what a goalie saved beyond what the shots he faced were worth, and the share of expected goals a skater’s team controls while he is on the ice.
The skater side — 725 players with their share of expected goals at 5-on-5, power-play and penalty-kill minutes — is built and switches on with the season. Team pages, the nightly card and goalie matchups follow.
Baseball is where our numbers go deepest right now: the MLB section has tonight’s bullpen report, plus a sheet for every pitcher and every hitter with enough of a season to read, split by the hand they face.
