I traded CMC for Kelce

I accepted the trade… i traded CMC and i got kelce.
was that a good deal?

For the other owner - yes.

As long as Carolina insists on giving CMC the same workload he had when he got hurt last year and again this year, then it will probably be a good deal for you. If they decide to lighten his workload, at least some, then he might last longer and be a very serviceable RB, in which case it was a bad deal.

I lean towards the first possibility, since Carolina seems hellbent on running CMC into the ground.
