Nope.
From the man himself, quoted from an interview in 2015:
“Bill Polian and I agreed when we first came together with the Buffalo Bills that we’d bring players only of high character to the team,” Levy said. “They are that. Now, we didn’t confuse that with personality. Some of them are very extroverted. Some of them are more laidback. Quiet. But they never placed blame on others. They always bounced back from disappointment. They showed up to work every day. Good family guys. Good citizens. They all cared about each other and they still do.”
He was talking about total character.
