Art Shell was 265 pounds. Gene Upshaw was 255. Mike Webster was 255.

Do you think it's a coincidence that the biggest offensive linemen tend to be left tackles? This is the blind side of your line (for a somewhat immobile quarterback, I might add).

There is no way Art Shell is taking J.J. Watt on the edge, or Upshaw is taking Ndamukong Suh or Geno Atkins on the inside. The three modern D-linemen I just named all are substantially bigger, stronger and faster than your three most important pass blockers. That would be a problem.

The opposite of this would happen:

I was wrong about Dick Butkus, though. I thought he was 230. I should have checked.
