I havent picked up nhl 10, but in 09 I've played a lot of games. I'd let one glitch goal go, if i see the player keep going for it then I bust out my strategy.
Whenever you get the puck, flip it out. Doesn't matter where on the ice just flip it out. And never skip a cutscene. Who cares if you have 5 guys in the penalty box. Usually they end up quitting.
