I just don't get the notion that he can't learn anything in AAA, as if he's graduated after dominating for 10 games this year (and not really more than much of the rest of the team at the time), and having a solid 18 AAA games last year. He's had barely more than a month in AAA.
I do think he would eventually right the ship here in MLB, but he can also make the needed adjustments in AAA without hurting the big league team, and get the O's that extra year of control. His odds of winning ROY have gotten a lot lower so I don't think that is much of a factor anymore either.
