He came to camp in shape for the cavs...And sometimes playing threw injuries isnt the smart thing to do...
Coming to camp in shape for him means under 370 pounds and able to run up and down the court a few times without throwing up.

He still can't play four quarters. If you look at just the past five years, he has missed 29, 7, 21, 21, and 42 games. It's a very clear pattern.
I agree it isn't always a good idea to play through injuries.
BTW, what's up with your boy LeBron?
