You might not like Iverson but no one can question how hard he plays. If that is what he said about Salmons, then Salmons is making it fairly accurate.
If you're going to elevate Iverson's word to that of carvings in stone worthy of adoration, remember he also feels practice is a total waste of time and meant only for lesser mortals.
Questioning how hard Iverson plays has less than nothing to do with the argument at hand.
