The loss was not due to Irving playing bad it was because W/B is so much better than the Heat or the Heat played one of the worst games of the year.
W/B took the game to the Heat from the drop of the puck until the final buzzer.
I do not remember one good scoring chance the whole game.
W/B is an example of a team that plays 2011 hockey - puck possession is everything, there is no chip it in and chase it they are in possession of the puck all the time.
The Heat not so much
