Canon 100-400L Eek uses it I think, he made some great aviation pictures with it.
It's alright for outdoor sports in broad daylight.. but anything else, you'll struggle to get high enough shutter speed.
It depends what type of sports the op is shooting just like antichrist- asked.
Also the 5DII isn't the best body for the job (not that it can't do it), just not as effectively as per say 50D/7D/1D
