Looks pretty even, but I don't think I'd do this if I were you. Your rotation consists mainly of pitchers who are doing well, but might come crashing down to earth. In a situation like that, it's comforting to have a reliable guy like Glavine to smooth over the rough patches.
Besides, if you have Hill, I'd wait a bit longer before passing judgment.
Maybe you could get this deal done for Rogers or one of your Hernandezes plus a 2b?
