i have been proposed D. Wright and Vlad for Berkman, Kazmir and Kemp. would i be giving too much? my roster is as follows: C: Martin, 1st: Tex, 2nd: Phillips, 3rd: Reynolds, SS: Reyes, OF: Berkman, Kemp, Hamilton, Util: Votto, Nady SP: Webb, Kazmir, Cueto, Jurrjens, Bedard, Myers.
i need the 3rd base upgrade, but is giving Berkman up too much? thanks for any advice.

I don't think giving up Berkman is a bad thing, but I think you're getting the wrong guys back. Wright is fine, but Vlad isn't needed on your team. You should get Wright and a starter. Or don't give up Kazmir and hope he stays healthy.
