I'm torn. It's a pretty awkward scenario, but I can't blame him if he doesn't come back this season. It's a very physical series, and Miami has some good defenders. It's a lot of risk and there won't be much confidence to build on if it's in his head and they put Lebron on him. I also think that his injury combined with not playing for a year makes him little better than what they have on the floor...
BUT he should be suited up because he could play a few valuable minutes. Even 3 minutes to give someone else a rest would be a great help.
