Dwyane Wade wasn’t himself this year and his knee (and age) had something to do with it. He will undergo surgery, which will force him to miss the olympics.
Also, his teammate Chris Bosh will skip the Olympics so he can rest his sore abdominal muscle that kept him out for part of the playoffs. I thought Bosh was moving around pretty well in the Finals, and the Olympics are over a month away. But I digress.
