ESPN has a whole story about this... basically making it sound like Hill cheap shotted Lebron and just about gave him a concussion.
"James did not remember the immediate moments after the blindside hit from Hill as both players went for the ball. James said he had a headache, but said he did not have tests for a concussion after the game.
"I've never had one of those hits since I've had on pads and a helmet. I don't know exactly what happened," James said. "I had a steal coming and the next thing I know, I was on the floor.""

From my viewpoint & the announces viewpoint, Lebron ran right through Hill while trying to go after a steal & the pass wasn't even going to Hill. I didn't go back & watch it on replay, but if Hill had football tackled him then I think he would've been ejected... yet neither was even called for a foul.
I thought the last 7.5 minutes of this game was officiated extremely one sided... they let the Heat hack, slap, push, run players over, camp in the lane, etc etc without calling any fouls and on the other side the Heat went to the FT line about 15 times in the 4th qtr. The only foul I remember being called on the Heat was when Jared Dudley pump faked a 3ptr and Wade jumped up in the air and landed completely on top of him (which was more of a football tackle).
EDIT: Just watched the replay & Hill sees Lebron coming & actually sets a screen in his path so that Lebron can't try to steal the pass. Lebron doesn't even see him & just plows right through Hill's pick... NO FOUL. Lebron was so focused on the pass going to Dudley that he doesn't even see someone standing right in his way. The best part is that Hill gets up and continues playing and Lebron lies on the ground for a few minutes acting like he got hurt.
