Is it a PPR? If so I'd stay put. You have RBs who can catch and you could start them all with your flex spot. Otherwise I'd look at packaging a RB like Barber or Smith with a lesser WR for a compliment to Jennings. I could see landing a Roddy White or better with the offer of Roy Williams and Barber/Smith. Might even get depth at RB if an owner is willing to do a 2 for 2 deal.
4th Post about the same trade with in 15 posts of each other just out right crazy man... COMBO them together!!
Package Roy and MB3 together and go after a top WR and a smaller replacement RB, Roy is far from WR1 material... get all the value you can out of him before he gets out on the field and loses it all..
