big trade offered, help out please!

[adamgreatjob]

i'm in a h2h league with these categories: runs, home runs, RBIs, stolen bases, avg, wins, saves, strikeouts, ERA, and WHIP. The lineup settings for the league are: C, 1B, 2B, 3B, SS, OF, OF, OF, UTIL, UTIL, SP, SP, RP, RP, P, P, P, P, 5 bench spots, and one DL spot. Here is what my roster looks like:
Batters:
Matt Wieters
Pablo Sandoval
Michael Cuddyer
Evan Longoria
Elvis Andrus
Shane Victorino
Ryan Braun
Yoenis Cespedes
David Ortiz
Drew Stubbs
Kelly Johnson
Cody Ross
Michael Morse

Pitchers:
Tim Lincecum
Ian Kennedy
Mariano Rivera
J.J. Putz
Sergio Santos
Matt Capps
Chad Billingsley
Anibal Sanchez
Matt Harrison
Ryan Vogelsong
Tim Hudson

My pitching has been in a bit of a slump and another player offered me a trade and I'm not sure if it'd be worth it. That's where you guys come in and give me some advice. This is who he wants to trade and who he wants from me:

Edwin Encarnacion, Madison Bumgarner, and Jordan Walden
for my Ryan Braun and Pablo Sandoval

That means I'd have 3 SF starting pitchers, but Bumgarner has been lights out and I'd probably drop Vogelsong. I don't know what to do! Help.

I would definitely keep your hitters. You arent getting enough and Walden isnt even the closer right now for the Angles, Scott Downs is.

[speeds102]

I would keep who you have. Your giving up WAY too much. Very lopsided.

[adamgreatjob]

even after encarnacion's grand slam? plus being named the cleanup hitter. and one more thing to consider, ryan braun is off the juice.

[jaredwilliams700]

Keep braun and sandoval for sure. That trade isn't even close. Walden isn't even closing right now.

[wazzeus]

Surely you jest. Or he jests, anyway. Beyond lopsided.

For Braun and Panda, you should get something along the lines of Longoria, MadBum and Kimbrel.

[Halo Homers]

Absoutely agree, keep your hitters. If you got a legit closer back, I might have a different opinion. Waldren is too iffy. Someone more stable like Papelbon, Motte, or Axford.
