Why the hell not? He couldn't cost more that 2 - 3 million.  He has the ultimate combination of experience and veteran savvy.  I don't think he's going to be unstoppable, but he is such a smart pitcher that he still has some upside, and I could see him having a final renaissance year.  At the very least he'll be better than Manny Parra.  I'd love to see Glavine and Hoffman hanging out together in the dugout, wearing the M.  Go get'em Doug.
