There's a difference between functional muscle and muscle for show. He didn't do it much this year, but earlier in his career he pushed around quite a few guys. And besides, the lower body strength is a lot more important for an offensive lineman than upper body.Ever seen the guy in person without pads on? Doesn't look like a football player let alone an offensive tackle. Has a serious lack of muscle definition in the upper body. Maybe he was a gym rat but just didn't have the DNA to define muscle.
