Carson owner here - I think by the end of the season you're not going to want to keep either. If you shed more light on your dynasty rules we might be able to give you a more informed answer. # of keepers, cost increase, etc.?
Unless you can keep a lot of players at a low cost you're going to have better options (Penny is the future there regardless of how they've looked since camp this year).
contract dynasty, 10 team, 28 active, 10 taxi, 8 IR. 0.25ppr

About this time of year I look at the teams who are bottom of the league, see who they might be willing to part with. Carson, Crowell, Mckinnon on IR, and a few others who were slated for big years that arent what was promised (so far). Because this is contract dynasty, if you dont grab them as a rookie or cheap in free agency to a large contract, the salaries are immense. Alex collins was a free agent this year and costs 11x what buck allen does. Carson and Crowell are both dirt cheap for their supposed rb1/2 status. Im not particulaly looking for immediate contribution this year, although that would be nice. Who do you think is the starter next year?
