Drop Lance Berkman?

[bujfan2030]

I had some computer issues and neglected my team for a month and I've dropped to the bottom of the standings. However I do have some real power issues and Berkman is not helping and He's killing my average. Would you merely bench him for a while or is it time to drop him.
