It's no secret that this year's defense was one of the best we've had. Over their last nine games, including the postseason, the Patriots allowed a combined 12 points in the fourth quarter. It used to be that if our defense gave up 12 points in the fourth quarter we'd view that as a moral victory. But with new additions Brandon Browner and Darrelle Revis, coupled with the emergence of second-year linebacker Jamie Collins, the Patriots defense went from 26th in 2013 to 13th last year. The Pats' chance at a repeat drop significantly if Revis leaves, but you have to believe the Patriots will do what they can to re-sign him. They need to take advantage of the championship window while it's open. Plus, the defense gets Jerod Mayo back next season. That can't be a bad thing.
