I've been trying to get Johnny Cueto in my fantasy league, and one of my friends offered me this deal:

Johnny Cueto and Alex Rios

for

Ryan Braun

This is my lineup:

C Ivan Rodriguez
1B Mark Teixeira
2B Robinson Cano
SS Hanley Ramirez
3B Ryan Braun
OF Ken Griffey Jr.
OF Josh Hamilton
OF Vernon Wells
Util Edwin Encarnacion
BN Corey Patterson
BN Mark Reynolds

SP Aaron Harang
SP Josh Beckett
P Ian Snell
P Jeff Francis
P Edinson Volquez
RP Billy Wagner
RP Manny Corpas
BN Francisco Liriano
BN Hideki Okajima

I'm worried about giving up Braun because I sacrifice a lot of power, and giving up so much for Cueto after one good outing seems like a big gamble to take, so I'm leading towards rejecting the trade right now. What do you guys think?
