Braves fans: Now that we're shopping Teixeira, is there any reason we can't get rid of 1/2 the bullpen too?

I thought it just stupid idea when Smoltz went down and everyone injuries, I thought Teix, Chipper and McCain can compare to Howard-Pat-Utley. Only they don't have any good pitching stuff and now all the sudden they want to sell Teix. I wonder who they gonna rebuild since Chipper and Smoltz both are very old.
