Wow... My prediction already came true... I said by training camp they'd report that he is back with 15 lbs of muscle... Didn't even take that long. He is the new AK (with regard to the report that he's bulked up in the offseason). What I didn't see coming was the old he's added an inch. He left a boy and a month later he's a man.
I'm only kind of joking. Cy is right about the weight... Many players lose wright during the season because it is so strenuous, but these tweets are definitely insinuating its muscle. He may be ten lbs heavier but the Only way to add that much muscle in a month is go to juice hard.
