The defense can only get better. Missing our one tech, and WDE doesn't help. Adding Melton, McClain, and Lawrence in the should help ALOT. These guys have taken a combine total of zero snaps. We know both Melton and McClain can push the line and get pressure. Lawrence is unproven at the NFL level.
With all that being said, all we've seen is our 2nd n 3rd string getting pushed around and when you see that through 4 games it can get to someone who is looking for some form of hope in any capacity.
I believe once we get these guys healthy and in action we'll see an improvement over what we've seen this past month.
