Does this improve my team?

[Grizzlies]

I have a couple of offers on the table where I lose Ichiro and Renteria and have to drop 2 players (Green and Sabathia?) to get D. Lee, C. Patterson, A. Ramirez and Brian Giles.

This was my team (currently in 1st place):
C - V. Martínez
1B - P. Konerko, S. Green
2B - M. Giles, J. Lugo
3B - S. Rolen
SS - J. Rollins, É. Rentería, J. Lugo
OF - V. Guerrero, I. Suzuki, J. Edmonds, S. Green
SP - J. Schmidt, B. Radke, Ol. Pérez, C. Pavano, C.C. Sabathia, Od. Pérez
RP - F. Cordero, M. Batista, L. Hawkins

After a couple of trades, this could be my team::
C - V. Martínez
1B - D. Lee, P. Konerko
2B - M. Giles, J. Lugo
3B - A. Ramirez, S. Rolen
SS - J. Rollins, J. Lugo
OF - V. Guerrero, B. Giles, J. Edmonds, C. Patterson
SP - J. Schmidt, B. Radke, Ol. Pérez, C. Pavano, Od. Pérez
RP - F. Cordero, M. Batista, L. Hawkins

Does this significantly improve my team? Should I drop Lugo instead of Green, which leaves me no SS or 2B backup and an OF I probably will never use?

Any help appreciated.

OK, I just pulled the trigger on a Renteria for Burrell deal (did I get enough?). So for now I will be plugging Burrell in at Util instead of Renteria.

So now my team looks like:
C - V. Martínez
1B - P. Konerko, S. Green
2B - M. Giles, J. Lugo
3B - S. Rolen
SS - J. Rollins, J. Lugo
OF - V. Guerrero, I. Suzuki, J. Edmonds, P. Burrell, S. Green
SP - J. Schmidt, B. Radke, Ol. Pérez, C. Pavano, C.C. Sabathia, Od. Pérez
RP - F. Cordero, M. Batista, L. Hawkins

If I make the other deal on the table my team would be:
C - V. Martínez
1B - D. Lee, P. Konerko
2B - M. Giles, J. Lugo
3B - A. Ramirez, S. Rolen
SS - J. Rollins, J. Lugo
OF - V. Guerrero, P. Burrell, J. Edmonds, C. Patterson
SP - J. Schmidt, B. Radke, Ol. Pérez, C. Pavano, C.C. Sabathia, Od. Pérez
RP - F. Cordero, M. Batista

So basically, instead of starting Ichiro/Konerko/Renteria/Rolen, I would start four of the following: D. Lee/Burrell/C. Patterson/Konerko/Rolen/A. Ramirez

Do you think that this would offset the loss of Ichiro?
