Belicheater is the greatest defensive mind in NFL history. The reason he finally found enormous success was lucking into a great QB like Brady, who took care of the offense. Jones is a middling talent who is better than a broken-down Cam Newton, but far from a Brady, which is what Belicheater needs to dominate the division again. And they still have no answer for Josh (except for gale force windy games).
They've only gotten worse over the off-season. While the rest of the division has gotten better.
