He's definitely referring to Marsh headlining a trade package but still, Rosenthal must be very high on Marsh to say that "they probably could land any starting pitcher they wanted". Marsh is slashing .295/.392/.405 as a 21-year old in Double-A. He's got the discipline, the ability to provide gold glove defense in center field and is a power surge away from being a top-50 prospect in my opinion. Rosenthal knows this and I'm sure many other organizations do as well.
