Zone defense saps the ability for the back 7 to come up and make plays. Yes we've got a new DC, new schemes, etc., but if the players can't comprehend the system or can't physically perform their responsibilities, it won't work.
The 4 man DL should be sufficient to slow down the run. But our DL isn't as athletic as expected. Playing zone is a killer. QB's aren't frightened by a zone defense. And
Our LB's are weak and can't plug holes and slow to assist and contain. Our DB's aren't strong to tackle/finish. (They also don't turn around to locate the ball on pass plays). Matthieu isn't what he used to be. He'll flash occasionally, but is needed to do more than that.Thornhill is still learning. His tackling skills need improvement IMO. He can close the gap at the LOS but at times seems out of control and will slide off the tackle.
