When the Browns hired Mike Pettine as their head coach last week, Manish Mehta of the New York Daily News reported that the former Bills defensive coordinator would likely be bringing a coach with him from Buffalo. According to Mehta, the Browns were expected to hire Bills linebackers coach Jim O’Neil as their defensive coordinator, assuming Buffalo let him out of his contract. Today, Ian Rapoport of NFL.com reported (via Twitter) that the Bills have indeed given O’Neil permission to talk to the Browns, adding that the interview is merely a formality. Here’s more from out of Cleveland, including word of another coach heading from Buffalo to the Browns:

• Chuck Driesbach, who was fired by the Bills earlier this month, will be joining Pettine’s Cleveland staff in some capacity, reports Mary Kay Cabot of the Cleveland Plain Dealer. The longtime college coach was working with Buffalo’s linebackers before he was let go.
• As Aaron Wilson of the Baltimore Sun tweeted this afternoon, Kyle Shanahan won’t be joining the Ravens’ coaching staff, and Rapoport believes that Shanahan could be a candidate for the offensive coordinator vacancy in Cleveland (Twitter link).
• In his latest MMQB column, Peter King writes that Pettine seems like the “ultimate compromise candidate” for the Browns, who aggressively pursued Josh McDaniels of the Pats. Referring to McDaniels as the “apple of owner Jimmy Haslam’s eye,” King says the team had multiple conversations with the Pats’ offensive coordinator about the possibility of him re-entering Cleveland’s coaching derby.
