Maudib... which side are you speaking of that may have more upside?
Also - I could probably switch out Cuddyer for Berkman and add in Franklin at SS.
I'm a big Pirates fan and love Cutch, but I also feel like I'd be giving up a lot of power (Hamilton and Fielder) and a bit of upside of Cespedes.
I think the McCutchen side might have the most upside. If everything went as well as it could:
McCutchen > Hamilton - Might be close but McCutchen wins because of SB and health
AGon > Fielder - Might be more equal but I think AGon has the edge if he can get to his peak
Minor, Morse, Berkamn > Cespedes - This wins because of sure numbers. Cespedes is the better overall talent here but I think Morse will surprise a lot of people.
Again most upside is the McCutchen side but it also has way more risk. Personally I would probably stand pat with Hamitlon and Fielder but like I said, I wouldn't be surprised if at the end of the season you look back at this deal and see the McCutchen side would have been a landslide in your favor.
