Trade help....WHIR

[da bears]

10 man league 6x6 wee add in total bases and losses for pitchers. Need a little help with my rotation I think and can acquire Cliff Lee for my Aramis Ramirez. My roster looks like this...
C-Wieters/Sandoval
1b-Votto/C Davis
2b-Aviles
SS-Rollins
3rd-Aramis/C Davis
OF-Kemp, Quentin, Hart, Milledge
SP-Liriano, Lester, Nolasco, Bedard, Cueto, J Sanchez

I am also pretty sure that he'll end up dropping Zimmerman if we make this trade as well who I think should be in for a solid year. DO you think I should pull the trigger and grab Lee? Leave a link and thanks for your input
