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 Adam Jones for Carlos Lee, and I'm leaning toward taking it.  I'm not sure how long the offer will be on the table, so I'd appreciate some good feedback if you guys have the time.  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    Carlos Lee (Hou - LF)
CF    Cameron Maybin (Fla - CF)
RF    Justin Upton (Ari - RF)
OF    Jay Bruce (Cin - RF)
UTIL    Bobby Abreu (LAA - LF,RF)
UTIL    Nelson Cruz (Tex - RF)

BN    Pedro Alvarez (Pit - 3B)
BN    Alex Gordon (KC - 3B)
BN    Buster Posey (SF - C)
BN    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    ---
P    Chad Billingsley (LAD - SP)
P    Brian Matusz (Bal - SP)

BN    David Price (TB - SP)
BN    Johnny Cueto (Cin - SP)
BN    Chris Tillman (Bal - SP)
BN    Scott Kazmir (LAA - SP)

I can easily slide Abreu or Snider into LF, and Adam Jones would take over CF from Maybin (until Maybin proves himself worthy).  Thoughts?
