Other than QB and Left tackle, the other position where we are extremely vulnerable is defensive tackle. For some reason, this board completely glosses over the dire straits the interior D line is in. Carter and Holliday are 3-4 ends, and not run stuffing tackles. They may be able to get some push inside in the pash rush, but we need to stop the run first and foremost. That's where it starts.
I was disappointed to read that Chester is out of shape. If he shows up to camp overweight, just cut him. That is unacceptable if he cannot work hard and do his job by staying in shape.
TBo is a longshot to stay healthy.
Take all these pieces together, and we are going to have trouble stopping the run.
