I think what I wrote is being misconstrued. I definitely didn't intend to insinuate that nutrition doesn't matter, ot absolutely matters. What I wrote is that I don't think there needs to be a marked difference in the foods that different players are eating, but rather modifying portions. They should all be eating healthy foods that promote muscle building and reduce inflammation. Obviously, there should be exceptions for individuals with other health concerns/allergies or for the odd lineman who needs to lose weight and still maintain strength or a guy who really needs to add bulk faster, like a LB moving to interior line, etc. But how many of those guys are there in a typical season?
What I think is overemphasized is the concept every single player needs to have a detailed individualized diet. That's not the same as saying nutrition doesn't matter.
