"I don't think at this point in time no," Vrabel replied when asked if Butler would be replaced by LeShaun Sims. "Because I don't think he's as good as Malcolm and the way he practices and where I see him going. We'll continue to evaluate that, like we do all the positions on the roster but I don't think that's necessarily the case right now."
Vrabel said Butler's struggles have been exacerbated by poor technique and not reading his keys.
"When you play man coverage you have to look at your man, and Malcolm knows that, and we talked about that, and we continue to practice it," the coach said. "We continue to coach it, and we try to show it to him. When we does that it's pretty good, it's competitive, it challenges the receivers. And when you look back at the quarterback your man has a tendency to go in another direction."
