I'm in a 10-team Dynasty League (year 7), where most stats count (not just your typical 5x5).  There are no contracts or minor leagues or anything involved - it's just straight Yahoo Fantasy Baseball.  Anyway, I've been offered the following trade proposal: Francisco Cordero and Colby Lewis for Mike Leake.  I am completely torn (normally I have an inclination on which way to go right away, but I keep going back and forth with this one).  I am not a fan of Lewis nor his ballpark, and I think Cordero is okay for this year but other than SVs (which I do need), he's not all that great, especially into the future.  Also, to accept the trade, I would need to drop somebody, which makes it an even tougher decision.  I'm looking for your advice/thoughts about any of the players involved.

Here is my team:

C    Matt Wieters (Bal - C)
1B   Lance Berkman (Hou - 1B)
2B    Dan Uggla (Fla - 2B)
3B    Ian Stewart (Col - 2B,3B)
SS    Hanley Ramirez (Fla - SS)
CI    Carlos Pena (TB - 1B)
MI    Jose Reyes (NYM - SS)
LF    Bobby Abreu (LAA - LF,RF)
CF    Adam Jones (Bal - CF)
RF    Jay Bruce (Cin - RF)
OF    Nelson Cruz (Tex - RF)
UTIL    Derrek Lee (Chi - 1B)
UTIL    Justin Upton (Ari - RF)

BN    Pedro Alvarez (Pit - 3B)
BN    Cameron Maybin (Fla - CF)
DL     Travis Snider (Tor - LF,RF)

SP    Chris Carpenter (StL - SP)
SP    Matt Garza (TB - SP)
SP    Jake Peavy (CWS - SP)
SP    Rick Porcello (Det - SP)
SP    Rich Harden (ChC - SP)
RP    Jose Valverde (Hou - RP)
RP    Chris Perez (Cle - RP)
RP    Joel Zumaya (Det - RP)
P       Chad Billingsley (LAD - SP)
P       David Price (TB - SP)

BN    Mike Leake (Cin - SP)
BN    Brian Matusz (Bal - SP)
BN    Johnny Cueto (Cin - SP)
BN    Madison Bumgarner (SF - SP)
BN    Javier Vazquez (NYY - SP)
DL    Erik Bedard (Sea - SP)

Thoughts?  Do I accept the trade?  If so, who do I drop to make room?  Do I make a counter-offer?  He doesn't have any better CL that I can ask for, other than maybe Andrew Bailey.  He also has Hamels, Kershaw, Verlander and King Felix, though I doubt I'd be able to get one of those guys in place of Lewis.

Also, on a side-note, just so I don't post too many times, what are everybody's thoughts on Leake vs. Cueto?  They both came out on fire, and Cueto has cooled down a bit since he first got to the majors.  Leake's not exactly a K machine, but all of his numbers are very good.  Is one much better than the other?  Is there a general concensus on who is better (fantasy-wise), Leake or Cueto?  I'm hoping to find some Reds fans here!
