Man ... if this were 12 plus teams I'd say stick with Trout. But there is so much talent that I think Braun stands out to me as a real find here. With Carlos Santana at catcher I think I take this. Just check on the health of Braun's achilles first.
I wouldnt do this deal braun has been fighting small injuries all year one is soon gonna land him on the dl i think and you have 2 great keepers in trout and posey. So i would pass
C Ruiz 1b Smoak 2b Altuve 3b Wright SS Aviles OFBruce,Cuddyer,Jennings UT Ibanez,A.Escobar B Arenciba/Markakis(DL)/Sandoval(DL) DL-J.Jay SP Grienke/J.Santana/Morrow/Haren/Dempster/Nolasco/Lilly(DL) RP Kimbrel/Myers/F.Rodney DL-Storen *2 DL spots
i'll assume you got posey and trout for below market/auction value. you're giving up some top building blocks. but, because you can keep six only, it doesn't look like you'll be diluting your overall keeper value too much. you got a TON of talent on your team to keep even without posey and trout - miggy, upton, jones, kipnis, adrus, tulo...
i know this might be a very unpopular opinion, but i'd also try to move santana over posey. this guy has been consistently good since he hit the majors.
go for the win this year and you won't be in bad shape for next year.
