It is relevant. They don't need to be that fat to do the job. In Lombardi's coaching days, a linebacker was about 210 pounds. The average one is like 260 now. In Lombardi's days a lineman was 250 pounds. Now some of them top 350. They just don't need to be that fat.

And Shaq is quite different because while Shaq is over 300, he is also more than 8 inches taller than even the tallest linemen.

7'1" 325 is nowhere near as fat as 6'3" 325.
