Name for the Miami Heat A.K.A. Dwayne Wade and Shaq. These two guys on the floor together are dangerous. They make a better team then Kobe and Shaq ever did...because Wade passes and Kobe is an idiot, see ball hogand huge ego . The combonation of D. Wade's dribbling, passing, and shooting mixed with Shaq's garbage points and rebounds equals an insane amount of points and wins. Therefore, the team is pretty much unbeatable when they're on their game.
Are you kidding me?!? D. Wade and the Diesel, the dynamic duo do it again!
