Reed, Banker, and Stewart should be canned. Stewart and Reed more than Banker. Stewart teaches terrible technique that can and easily be fixed IMO. And Reed was a head scratching add to begin with. Possibly another OL coach instead of Reed or even a CO-DC who does most of the recruiting.
Also, better play calling. I understand we aren't as good at running the ball that's fine. But when it's 3rd and short, why pass?
