I don't know. Maybe the undefeated team that lost in the superbowl. That would be the only team of the Patriots his past 20 years that had the most talent and they finished runner up.
I believe Belicheck could take many teams in the NFL and have them in the playoffs.
I don't believe Brady would have as much of an impact as Belicheck with helping other teams win. In fact, I stated before that to me Rodgers is clearly the better QB and circumstances are the reasons Brady has won a bunch of superbowls to Rodgers 1.
If you take the 32 NFL teams and had Brady be their QB and was able to redo with Rodgers as the QB, it is my belief that 24+ of the teams would do better with Rodgers than Brady.
