That's not really much of a rebuttal.
Here's the full quote:
"Ability without character will lose. The Bills are going to be a team of high character. That stamp I will push very hard. I hope we can convey that to our fans and project something very special to the rest of the nation."
Also, here's a link to a program and educational brief from a Marv Levy lecture.
Heart of a Hall of Famer Series: Marv Levy - Extreme Networks
Notice the items listed under the learning objectives section. These are what I think Marv meant by character. It sounds to me like he wanted to build a team of players that the community and the nation can be proud of. I'm not sure how proud you can be of wife beaters, bullies and murderers.
If you think you know something different the say what you think it means and back it up with some research. Otherwise, your argument is basically worthless.
