If the Sox asked for Chourio in a package back for Cease, I'm sure Arnold would laugh hysterically and then politely end the conversation. Even Misiorowski would be a major stretch for us to give up on for a guy in Cease that definitely pitched more like a mid-rotation guy this past year. I think the only way we'd give them "Miz" as a headliner is if our FO really didn't think he had the potential to become a TOR type arm in the big leagues. If you thought his future was definitely as a high leverage relief arm - then maybe you include him as the main piece going back in a deal for Cease. But, I think our FO still thinks that "Miz" has starting potential in the big leagues. So, I don't think there is any way we'd trade either of those guys for Cease.
MAYBE they would consider Quero as a headliner, but didn't the Sox just trade for the other catching Quero prospect from the Angels last summer? So, I doubt they'd have much interest in him coming back as the main piece.
I think Frelick could absolutely be a main piece going back, as was suggested above. I think we'd have to throw in someone in the 6-10 range from our prospect list (maybe Gasser or C Rod), and then maybe someone like Logan Henderson?
