that's complete bull sh-t. they had 2 days off. they have been thru everything as a hockey team. losing game one of a best of seven has no effect on game 2 win or lose.
Iam not saying it should have any effect but early on it is possible. They are humans after all. losing 1 game is no big deal but in 3 OT and giving up lucky goal(s) can sapp a lot of mental strength.
