Okay, here is my take on the elbow. I think it is hurt, I really do, I haven't used it as an excuse and I still won't, the Celtics are playing great.
I honestly think it was hurting him pretty badly in the Chicago series when he shot the left handed free throw. He asked Brown to take a timeout and Brown didn't. He didn't want to hurt his elbow more so he shot left handed.
Now he will not use his elbow as an excuse, the media might, but Lebron won't. But, not being able to use the elbow as an excuse has caused a lot of media to call him weak, accuse him of conspiring against his coach, accus him of quitting, etc. Through all of this he has still not mentioned his elbow. He could easily come out now and say his elbow is really messed up and all would be forgiven, but that's not how he plays. He plays through injuries. But, this one may actually be getting the best of him which is affecting hs demeanor.
I could be completely wrong, I could be right. Who knows? All of these answers will come in time.
