re: Numbers for Freshman, Transfers and Changes. Plus New Weights

I think a lot of it may be bad weight for the big guys and making way to build muscle. My real question is why some of our defensive backs CAN'T put on good weight and muscle. Being a good player is more important than a number I know, but it can't help DJ James that he literally stayed at a 170 pounds even though he had access to a college level weight program. He's a first rounder if he was 185-190 at least. Anyway we have several defensive backs that barley make 180 and I wonder why? Could it also be more about the muscle and not the number? Not an expert, just asking for opinions
