Conner in dynasty

I have bell and Conner in a dynasty auction. Obviously have Conner dirt cheap so I am trying to gauge his value past this season. Does Pitt do away with bell after season And move on with Conner ? I have a guy considering trading me Odell for Conner and mark Ingram. Keeper costs would be 28$ for Odell. 22 for Ingram and 5 for Conner. For this season my WRs and flex would be aj green, mike Evan and Odell with josh Gordon bench. But my rbs until bell came back would be just freeman and Jordan Wilkins. 12 team leagUe
