I would sign this guy and dump McCargo. Johnson was a starter for Indy for the last 4 games and was surprisingly cut last week. The Colts say it was performance, but it may also be related to a grievance filed by Johnson the last time he was released by them. Johnson probably has a much brighter future than McCargo at this point.... Per a league source, Johnson was among six defensive linemen who worked out for the Bills on Tuesday. The others were Marlon Favorite, Antwan Lake, Joshua Leonard, Langston Moore, and Rodrique Wright. This might also mean Kyle Williams may be hurt worse than we've heard.
