Fitz won't follow his lead blocker. When he does, see the second half of this game. Nearly 100 yards on the half, few negative plays unless the middle of the line or the te fell apart.
Knowing a team can't run the ball brings continuous pressure on a young qb without many actual starts to his name. And this qb has one experienced outside receiver who can make the moderately difficult catch, a couple mediocre dudes, and a te who can't block. The number two rb and wr being out is probably not helpful.
