In Regulation mode have 3 of your teammates killed and still win the game.

Now you have to switch from Easy mode to Regulation mode for the next couple achievements. The best thing to do to get this one, is to score as much as you can in the first 2 or 3 periods to cushion your lead. Because, once your players are killed and replaced, the reserve players are much slower. All you have to do to get a player 'killed', is make sure he is holding the ball at the end of a play where the ball was "CRITICAL". You should be able to get 3 killed easily within 3 periods or so.
