I own both a 7D and a 5DII. When I shoot sports, the 7D is my primary camera.
My 5DII is an awesome camera, but it does feel like Canon went out of it's way to limit in a few areas to keep it from cutting 1D/1Ds sales. Now I sell stock, and the 5DII is my primary for almost everything I shoot besides sports. I have never been unhappy with it's AF system, I just don't expect it to be a 7D.
In any case if sports was my primary focus, I'd buy the 7D way before a 5DII. Strap the best 70-200 you can afford on it and you have a sports machine gun rivaled only by 5000+ camera, and then by only a small margin.
