First, thanks for the help with mine.
Now, I have a question: Who are your 4 keepers for next season, as is, before the possible trade?
Pujols, Heyward, Gallardo/Oswalt, Strasburg?
So after the trade you're looking at:
AGon, Cruz, Verlander, Gallardo/Oswalt?
Out of those two options, I'd take the first.
Pujols > AGon (Yeah he's struggling and AGon is on fire, I don't care - he's still Pujols. Check the history.)
Heyward > Cruz (It's a keeper and Cruz = DL. Heyward is a machine.)
Gallardo < Verlander (It's closer than it looks because Gallardo is 3 years younger than Verlander and this is a keeper.)
Strasburg = Gallardo/Oswalt (It's a keeper... you have the best pitching prospect in the game.)
I'd take the Pujols/Heyward/Gallardo/Strasburg keepers and sit pretty knowing you have the best young hitter/pitcher combo in the game coupled with the league's best hitter and a stud young SP ace to boot.
Hope that helps.
