Why? He was the head coach of a team. He built the teams. You are cherry picking. Oh umm he has to have a great team with a good backup then lets compare...2020 was the team that Brady had in 2019, minus a beat up edelman, and you had a former mvp QB. 2000 we had a lot of the players that were on the early pats superbowl teams, I listed them off. The magically winning didnt start until Brady became the QB. In years Brady didnt play, 2000 2008 2020, they didnt make the playoffs and in two of those years they had a losing record. I am not sure why its so hard to say a coach has a worse record without a hall of fame QB. Hell if Jones got hurt right now and Hoyer played the rest of the year, do you think everything stays the same? Bill is a coach, he can call the best plays ever and if you have players that cannot execute you lose. Bill does not throw any passes.
So no, Bill's record if he never had Brady would not be as good as it was with him. Sorry to shock everyone with that statement.
