I have a hard time picturing a guy who was 330 pounds in college, getting to the NFL, with unlimited money (by comparison) and suddenly going, I'm going to lose 40 pounds of weight.
Just feels like a far stretch to me. Most guys get bigger when they hit the NFL, not smaller. Teams do weigh ins to make sure a guy isn't overweight, not underweight.
So while none of us know for sure (Which seems really stupid, someone could ask the guy) I think logic certainly has me leaning hard in one direction. And why the hell would there be a gag order on it, unless it was ordered by the team? Why is the subject taboo?
