Yeah... I think you're only going to get one premium, close-to-the-majors guy in dealing Skubal...
I have my eye on a couple guys because that's who I want/ am targeting. But the other team has to agree. If not... move on to another team, or if there's no deal good enough to be had then, no trade. But outside of one premium guy who might be a double-A/close-to-the-majors guy.... the rest of any prospect package will be lower level guys...
If I want to send Skubal and Soto to the Cardinals or Rangers for Walker or Jung (first they have to agree to that... but on that end... I believe both those teams have a serious interest in Skubal if the rumors are to be believed...?); we'll get more prospects than just the one... but those extra prospects will be the A/Low-A/Rookie league guys.
With potential.
