Seattle's offensive line is garbage, and they will be missing their top Guard, and their top tackle is questionable. Then factor in their quarterback isn't even 100%. The Patriots aging defense will be a lot harder to expose when they Hasslefag or Sen nica wallce doesn't have time.
On the other side of the ball, Seattle has no pass defense, and Cassell should have 300 yards.
