‘“He was a great head coach, but I couldn’t get my hands on him,” said ex-Bills safety Pierson Prioleau, who joined the Redskins as a free agent this year. “Having him in the meeting room with you, having him teaching you things on the field, having him teaching you 100 percent of the time on defense, I love that as a player.” Williams says he has learned his lesson. He is at his best when he is hands-on, and he wasn’t in Buffalo. Next time, he’ll hire someone else to handle the offense so he can work one-on-one with his defensive players.’
