$20M for an extra year of arb? Highly unlikely, and even if it's so, that would only happen if the guy was putting up MVP numbers. Not to mention it's maybe up to some large number like that, 6 years from now, if ever.
I actually prefer keeping him in AAA past Super 2 - which by the way just passed the other day. I am just saying, you have a really exagerrated sense of reality here.
