Out of the guys on my team, what is a good offer for Brian Westbrook?

I have: Ben Roethlisberger, Phillip Rivers, Wes Welker, Marques Colston, Donte Stallworth, Vincent Jackson, Frank Gore, Laurence Maroney,Jesse Chatman, Deshaun Wynn, Jerious Norwood, Selvin Young, Chris Cooley, Jason Elam, and Chicago Defense. I'm in a 1 QB, 2 RB, 3 WR, 1 TE, 1 W/R, 1 K, and 1 DEF league. My RB's just aren't producing for me.
