GLENDALE — Maybe it was watching Connor Hellebuyck smash his stick in half over the crossbar after getting scored on by a teammate during Thursday's morning skate in Denver.
Perhaps it was Dustin Byfuglien breaking his lumber on the boards that night after Jacob Trouba stayed on for an entire two-minute power play, leaving the veteran Winnipeg Jets defenceman glued to the bench and likely seething over coach Paul Maurice's refusal to put him back on the top unit.
Later, Byfuglien was caught completely out of position on the overtime winner by Colorado, and apparently carried his anger over into the room following the game, a source told me Friday.
