It really is impossible to judge when his wardrobe is completely different compared to then.
Currently, he is either covered up or showing way more than he did before, which might make him look smaller than he is compared to then.
Also, he regardless of whether he was 250 pounds then, he sure wasn't 250 pounds of pro bodybuilder. No way. He was not "bigger" then, no way. Right now, he looks like a mini levrone - back then, he simply looked like a dude who juices (a big dude, but not a big pro).
