Help with this trade offer. Please?

I am desperate for a QB, I have trent edwards and Sanchez. I was offered Cutler and slaton for Fitz and kevin smith. I really can't see myself parting with fitz and I really like kevin smith but I do need a qb. I think sanchez has been decent enough but cutler will be more consistent and will produce at least 20 more points a game than sanchez, i think. As for slaton, I have a feeling this is his sopre slump but even it's not I still like kevin smith. by the way my other wr's are wes welker and patrick crayton, I lost gonzo in week 1 with an injury and my other rb's are jacobs and knowshon. do you think it would be stupid to accept this
