There were a lot of K.C. supporters on here last year but I think even they are fed up with him. When it comes down to keeping Moore or Fasion on the roster, I think you get rid of K.C. and let Moore and Fasion return kicks and punts. Plus we have Taylor and now Williamson(who has speed).
Even if he is a bust, I don't think we can afford to let him go. He has speed, and....and....uh that;s it. So let him stay on the roster as 5th WR and return kicks and punts. If a WR goes down maybe he'll get another chance to prove himself.
If he gets in trouble with the law again though, cut his jiggly butt.
