Jetster, interesting but depends on the co-operation of two other teams.
Would Shanahan take the chance that he can find another quality B/U.
maybe getting Minn to give Harvin, a 3rd and Joe Webb and send both the pick and Webb to the Skins. Webb has the skill set to run the spread option and would be a good fit as a back up. This way Shanahan gets a qb that is a fit and gets a 3rd to replace the 4th that he spent on Cousins.
