I doubt the Bills did (1) in good faith. I am just surprised that McCargo, the docs and the coaches did not explore the possibility that a medical problem may be preventing him from playing all out. It very well might be that his internal drive is not strong enough. But, wouldn't there be pain due to this medical condition ? And wouldn't McCargo want to find out what it is about ? Forget that he is a professional sports player. Heck, if I had a nagging pain, I would have it checked out. What gives ?
