The media is the only one that has said anything about the attitude not Harbaugh or Mcalister. It's all media speculation. He did have an injury and I believe he violated a dress code. After the dress code violation he was too hurt to play. I think people are reading too much into it. If he is going to be a locker room cancer then trade him but, I don't see Mcalister as a cancer just a little nuisance at worst.
