Career record without Brady is sub .500, I don't agree that they aren't talented enough to win the division even without Brady. If Lewis and Edelman come back healthy that will give them an abundance of options. You may not like them, but all those options play above their talent level because of rub routes, scheme and the NFL rules on defensive contact. Every snap they let 4 or 5 little rabbits out of a hat and one of them is bound to be open for a short pass and some YAC. They also acquired Bennet who gives them a nice two TE set to soften the blow with Jimmy G. operating in the redzone.
Their defense has enough talent and should be good at stopping the run which will help them in divisional games. Collins, Hightower, McCourty, Butler are all above average players. Malcolm Brown was coming into his own as a rookie at the end of last year as well. Their weakness will probably be their pass rush but outside of Arizona none of the other 3 teams will beat them through the air. The Bills vs. Pats game will be a pick em if both teams are relatively healthy.
