the thing i find about Bosh
is that he DOES play with toughness. Sure he's not as physically strong as most of the bigs in the league, but CB still bangs with them, he still fights and brings down boards. Does he take a lot of jump shots? yes. but he has a good jump shot. On the flipside, he takes it inside probably more than any other raptor too. How many times does he get to the charity line? a lot.
Again, he may get overpowered on numerous occasions, but the man still continues to fight down low and is pretty succesful doing it.
He may lack bulk - but i say this: He doesn't lack toughness.
