Do GMs often leave cup winning teams because they're gung-ho to rebuild somewhere else? I think Yzerman enjoys winning cups too much to go back to rebuilding, wherever it is. Someday Vinik will fire him. That's when he might go home, if the circumstances are right. But I don't see why he'd leave at the height of the success he's worked hard to attain, just to go try to do it all over again.
