The game winning goal was on Max - his unwillingness to physically engage was front & center for everyone to see.
It's the most basic of plays, take the man at the point, u don't cheat in the playoffs. When u don't score, and I agree the focus on Max makes it very difficult to do so, u have to find other ways to contribute starting with elevating intensity & work ethic - a warrior mentality.
While true, it was a high risk move. If his poke check worked, he would have scored at the other end as no way McDunceagh would have caught him. Petry also left Nash alone in the corner.
