I don't this deal doing too much for you, runrickyrun makes a good point about if anyone else is more desperate for a QB. Depending on how your league looks I could see someone having a use for Freeman, and he would likely give up something a lot better than DHB since that's essentially all you're getting. No way under unless Brees gets hurt are you starting Painter over him.
