Good post. I agree with your idea about defense from forwards but disagree, mostly because Hossa is an absolute demon on the backcheck where Parise isn't. Hossa overtakes people and just bodies them off the puck and/or strips them. Parise's not really big enough with enough reach to do the same.
Parise is the best boardworker in the leauge. He always wins loose puck battles. He is the perfect complimentary player for your star player.
