I personally would start with an offer of Tulo and Hundley for Kepler, Polanco, May and one of Meyer/Arcia/Vargas. In that deal you get a couple prospects who could crack the top 100 very soon, a mid rotation cost controlled guy in May, and a high risk.high upside guy in Meyer/Arcia. Or maybe you offer Stewart+Polanco+May, I'd be ok with that as well. Stewart is a top 30 prospect, and you still get some close to ML ready help with Polanco, and a ML mid rotation guy in May. It would suck to get rid of Berrios, but at the end of the day I would be ok with it, especially once Berrios gets up to the ML level and gets shelled in Coors
