People need to get a grip. It's only the end of June. He probably took most of May off, just doing light work outs, and healing his body.
He's just got back into Boston to work on his body. He's always going to be on the heavy side, because he's a bit wide in the back end. Everyone's body type is different, and it may take a couple years before they really find what works for him. But thats his job now.
Now if he's the same way by training camp, then people can jump on him and his work outs, and weight. But give the kid 3 months of working out 5 to 6 days a week and I bet there is a difference in either his body or game.
