The offer is
Me Recieving:
John Maine
Willy Taveras
Nick Swisher

Me Giving Up:
Carlos Lee
Nomar Garciapara

Normally, this is a no brainer. But I'm having second thoughts. What do you think? I am short on pitching, but i need Lee's RBIs. I need a first baseman also. Is Lee's production enough to make me deny this trade? What should I do?
He also has Brady Penny, Brandon Webb, Jason Marquis, more high caliber pitchers.
I have an awesome infield minus first base, and my outfield is decent, but I need Lee.
Ahhhh, Help!
