Ironically his record for that one year in Washington was the same as his first year in Green Bay (although he did add a pair of ties in Washington).I didnt say Lombardi wouldn't be successful, but that he wasn't after he left and yes, sadly, limited data.
I guess the point I was trying to make is that great coaches need great players, as much as great players need great coaches to obtain successful team results. In the case of BB and Brady, things aligned for them both quite well In New England. Sure Brady won a SB without BB, but I wouldn't put it past BB to do the same.
