We've PLAYED better than them, gotten the open looks, made stops on defense, we've just shot horrible...plain and simple. Miami on the other hand, hasn't played that spectacularly (they've done really well, don't get me wrong), but has made an insane amount of shots...including sick amounts by wade.
Just look at game 4 (I think it was) where wade jumped, was spun around by a defender in the air, fell on his back, and on the way down sunk a shot. That shit just doesn't happen, it was nuts. And for whatever reason, drive, energy, luck, they're making a lot of shots...more than they "should."
