I agree with puckfancy...Everyone needs to step-up!!!
But, if were to look back at last year's playoffs, those that absolutely must step-up are Alfie, Spezza, Heatley. None of them turned the intensity level up last year, none of them drove to the net, none of them were crashing and banging in the corners!
Granted, the crash and bang style of game is not what they play (at least Spezza anyways), they need to be at least a little bit physical. The game tightens up in playoffs and if you aren't going to stand your ground, fight position, or be the first to the puck your going to be useless in the playoffs - no matter how much skill you have, or how many goals/points you got in the regular season!
