McCown is visiting with the Bills on Monday with the hope of reaching an agreement on a contract after he was recently released by the Bucs, ESPN's Adam Schefter and Mike Rodak report.The Bills are looking for a new quarterback following the retirement of Kyle Orton at the end of the 2014 season. McCown struggled in his only season with the Bucs, but the Bills are likely intrigued by the success that the veteran had with Chicago in 2013 (13:1 TD:INT, 8.2 YPA) while filling in for Jay Cutler.
