I don't mind that plan. I don't think Shark is worth a ton tho. I wouldn't send any top guys for him. He's a mid tier SP signed for a season. He has upside for next year, but he's still basically a 4 ERA guy. I don't care what Beane was willing to give in the heat of a pennant race. I'd give him 2 maybe 3 of WMB, Marreo, Bradley, Brentz, and Nava.
It'll catch on somewhere if true soon enough.
