I certainly hope that I'm wrong, but I think the Pats will score less and give up more this year than last.
My novice opinion so take it fwiw.
I was rewatching the 3rd preseason game vs the Panthers and there is some good defensive stuff the Pats were doing in it.
Some of the game seemed experimental with double stunts etc.. and leaving the edge wide open. But during the end of the first and into the second quarter they looked solid if not great.
1. Shelton looks solid at NT. This is, imo, is the key improvement over last season. He can two gap which means the LB's have less to worry about than they did last season.
2. They moved Malcolm Brown around during the game. Either on the left or right side of Shelton. Looking for match up opportunities during the game. Last season he was asked to be a quasi NT with 3rd down DT's anchoring his left or right side. That didn't work out well.
3. During one series Davis sealed the left side of the line perfectly, Brown pushed the LT back into Cam, Hightower got through a gap and flushed Cam out of the pocket. KVN chased him out of bounds for a two yard gain. It was perfect..
4. During another series they handed off to McCaffery. Their intent was to create a cutback lane but Shelton strong armed the guard, Davis kept the edge sealed by avoiding the TE block, and KVN plugged the lane. MB and Hightower held the left side of the Oline while Wise broke through and Chung maintained the edge. KVN, Shelton, Wise and Davis were in on the tackle.. (See image below)
So I disagree. I think this defense will be better if not much better than last season and give up less points.
I've circled Shelton handling two Oline guys which allows KVN to plug the lane. Good stuff.
