For one, whoever does this seems to change it too much. One year they made a change and it was all over the place. Lapuaho was 2 inches shorter and lost weight, then they changed it back. Some dudes put on a ton even if it wasn't real. Some guys never gained weight on the list even though from their own mouths and the coaches, they did.
There's already one here. Balderee said he was slimming down a bit to become a better receiving option. I doubt he went up to 250 if he personally said otherwise. Somehow Fred Warner hasn't gained any weight in like 3 years even though he clearly keep getting bigger and again, he personally said otherwise.
I never know when to trust the roster. They're kind of bipolar with their updates. We'll probably see changes again even if there really aren't any.
