There has been lots of Al Golden to BC as Defensive Coordinator talk the past 24 hours. I have been wrong on these things many, many times, but I don't think Golden is coming. Forget about the mismatch of styles or Golden serving as a threat to Addazio's position. I don't think it is happening for the very simple reason that Golden just moved his whole family back to New Jersey. Just moved, as in less than a month ago. New school for the kids. New house. Everything. Given that, I don't see him as the type of guy who is going to take an assistant job a few weeks later.
Whatever problems Golden might have as a head coach, he's been a pretty good at managing his career. His biggest mistake was probably not taking the BC job when Miami was still being investigated by the NCAA. While serving as a Power 5 DC might help rehab his profile, he might be better off sitting out a season and trying to get a head job next offseason. He might even be a candidate for BC should Addazio struggle again.
Maybe I am reading too much into the family and career issues, but once again the timing seems off for Golden to come to BC.
