I am not sold on the Heat. Adding bigger names doesn't make you a better team. They already had their stars and go to guys in Shaq and Wade. Adding 2 flashy players that don't play defense does not make them a better team. I think Damon Jones and Eddie Jones were much better role players for what the Heat needed than Jayson Williams and Antoine Walker.
BUT...who else is going to challenge them in the East? I think Indiana has the best shot.
