I agree, with screens and reverses, it becomes an asset to be smaller. Harder to hit, and easier to get lost from the defenses in the commotion of a play while setting the screen and/or reverse.
TD can only assemble the talent. If the players dont play or the coaches dont coach then they get replaced. I think TD has done a reasonably good job of putting talent on the roster.
With the exception of Bledsoe (Should have cut him when it was no cap hit) he has done an above average job.
Certainly could help him practice his delayed blitz pickups ! I like that he is 6 foot 5 and 311 pounds. He should be able to anchor that center position and not get blown backwards.
