Similar point to be made with Nazem Kadri.I remember when Toronto was trading Phil Kessel. Many fans said no way. Not for any price. Doesn't hustle. Quit on Toronto. Goes to Pitt and plays a major role in winning 2 cups.
Jeff Carter also pushed to get off the CBJ and won 2 cups on the Kings.Similar point to be made with Nazem Kadri.
Some guys just aren't wired to be a 1C on a Cup winning team. But if you put them in a complementary role, look out. Not to mention, it also means your team has some serious depth at that point.
