Depends on who you ask. Even though he was throwing stronger than ever more than one anti-Dolphins people were making fun of how fat he has gotten in the offseason.
I saw reports and a pic that Austin Jackson looks like he is in really good shape coming off his offseason ankle surgery. Hope it translates tot he field.
In such a short period of time between the end of season and now, he would add on muscle along with fat. He can get the fat down by the time the season starts once he got the muscle size he wanted. If he showed up to minicamp 20 pounds heavier of only muscle, he would fail a drug test before he started urinating.
