Look at Al's weak body in that picture. He just doesn't seem to do much in the offseason. I guess he slimmed down last summer, but I see
little to no muscle growth. You've got to bulk up, and get ripped to play C at a high level in this league. Unless you are super talented, which Al is not, he's not showing much desire to keep his starting 5 role.
At least Millsap works hard every offseason.
