Belichick wasn't much of anything until he hooked up with Tom Brady. 1st year was sub .500 with the Patriots. They caught fire next year largely with Tom (and a little help from Bledsoe) and won the SB.
Yes, coaches (or anyone else) should be judged individually, but it would be silly to ignore the environment they came from. The recent Browns "era" has been anything but consistent or impressive and the past two O-coordinators of ours that were from Cleveland have resembled that.
True but you have to wonder if he has learned from his mistakes and realize that he is apart of the Ravens' staff and learned enough behind a true GM in Ozzie Newsome to be a good GM
