I didn't see the replay today, but it looked like Heat defender got across Manu arms when he was ATTACKING the basket. This is what Manu wanted to do, drive, get fouled / get lucky(pts) or make free throws. At least NBA should release article that refs made mistake.
But if thats what he intended to do, then it was a massive mistake. Never leave it in the hands of the Referees. Especially when' they've been letting alot of things slide.
