Shot chart

Every shot attempt, computed from the league's play-by-play coordinates. Mammoth attack left, Bruins attack right, all periods folded onto one rink. Attempts are plotted where the league recorded them, so the 1 mark in a team's own end is an attempt logged from there: empty-net shots, long dumps on the net. Boxscore shots on goal: UTA 21, BOS 23.

UTA in red BOS in blue goal shot on goal missed blocked Mammoth 21 shots on goal (1 goal, 14 missed, 24 blocked) attacking left; Bruins 23 shots on goal (4 goals, 12 missed, 13 blocked) attacking right.

Attempt share by period

Mammoth took 55.1% of the shot attempts, and 56.8% of the 88 attempts taken at 5-on-5. An attempt is a goal, a shot on goal, a miss or a blocked shot; CF% is the share of them belonging to the Bruins and FF% their share of the ones that were not blocked, so the Mammoth hold the remainder. All situations unless the 5-on-5 figure is named. All 32 teams
