I think Petey plays a better two-way game. AM is a better goal scorer.
Based on the metrics, stat line and analytics you have to say AM is better.
HOWEVER, based on what Petey is doing in the playoffs....and how much he's improved over these three series, i bet you that by the end of next season, he'll have a stat line very much in line with AM while still providing better two-way play.
Right now AM is better. However my guess is that Petey takes him next year.
I dont know what it is, but watching AM play, he kind of has a i dont give a crap attitude.... so much natural talent there, just needs to commit more maybe?
