Three things really wrong.
Penalties - Way too many penalties. Stop drives for us, continue drives for opponents.
Running Game - R U N the ball. Shovel passes, direct snap, tons of options but if the linebackers are not being held near the line they are either blitzing or covering. That and the d-line can tee off on the quarterback for 7 sacks a game.
While Harris has good passing numbers, there are things he does that are far too predictable. I'm sure every defence in the league has figured out he always rolls right. The short and shovel was there all day yesterday. It doesn't have to be a bullet pass down the field. Toss it over the linemen to Wilder standing all alone 5 yards in front of you. If we got a pitch and catch game going with Wilder I'm sure it would be effective.
