Another thing you have to remember is that the bread-and-butter for strength and conditioning coaches is football particularly the line positions. So, they're not really worried about low body fat percentages.
Ok, 1. Rippetoe isn't a real strength and conditioning coach. He's a crossfit strength coach. 2. He's admitted he's never worked in a team environment.
As a Strength and Conditioning coach and depending on the height, weight and athleticism of the lineman, it absolutely makes a difference just as much as any other position.
