Yeah while I'd be scared at the thought of trading Stroman for all pitching prospects, a package of Garcia/Contreras/Gil is probably fair. Not sure Cashman would trade all of that, he's usually pretty stingy trading prospects, but he knows the Yankees have a window right now and the Astros want Stro too, so maybe he'll bend a bit.
As long as it's not Clint Frazier coming back, I'm good.
