First of all, it is a ridiculous take, pretending to have any idea what kind of shape he is in right now. Secondly, I would rather he work on his footwork, touch, timing etc right now, rather than doing curls so that he looks good in T shirts for fans who want to see his muscles.
This is the off-season, and I am just happy to see he is working on his craft putting in the time to keep becoming a better QB. He has several months before he has to worry about getting back into game time shape.
