I think Peca would fit in really well. He knows Pat Quinn, Owen Nolan, Joe Nieuwendyk, and Ed Belfour from the Olympics. He is a respected player in the league, just not by Leaf fans. I think he is a quality player and a guy like him is essential if TO wants a chance to win the cup. He plays great D, wins a lot of draws and defensive zone faceoffs, and is a solid penalty killer. If he chips in a few goals, bonus.
Guys like him are assets in the playoffs. He just needs to get out of New York, if the Leafs could get a defenseman like Niinimaa or Aucoin as well they'd be poised for a run.
