I don't know about other fans but I feel much better about the Patriots now than I did after the 2009 season ended. The signs coming from that season pointed to team that lacked team leadership in the lockerroom, had become one dimensional offensively, couldn't win on the road, couldn't win big games, and couldn't beat any good teams. After this season they had developed new leaders throughout, remade their offense to a much more balanced attack, won consistently on the road, won big games, and beat all of the best teams in football. Additionally they went with the youngest defense in the league and by year's end it had payed off and they were making real strides in the right direction.
The Patriots have needs, they aren't a finished product, but they have set themselves up to be a serious threat and contender for the remainder of Brady's career. They will have to continue to make the right moves to keep the OL at a high level and improve on both sides of the ball, but the groundwork has been more than laid and anyone who can't see that hasn't been paying attention.
