Lol. It doesn't take a fitness buff to know that you need to be in a different kind of shape to compete against the elite of the elite in a professional contact spot vs. competing in competitions for people with disabilities or in NCAA wrestling. NFL coaches and NFL players have explained over and over again that there is a big difference from being in shape and being it football shape.
But, you're probably not much of a football buff are you?
And you have absolutely no information about what kind of shape Miller is in other than one off hand comment by DA. So you are really just grasping at straws.
And what is a "fitness buff" anyway?
