dude is way past his prime, i'd be shocked if he could make an NBA roster at this point, he'll have to do some major "conditioning" with lebron first.
and the cavs already have several poor athletes on their squad. if an ancient Big Z does get minutes, it makes them even slower.
probably would be more of a player/coach, though, just wants that ring after all his years there, can't fault him for that, by all accounts he was a class act.
