It would be to clear cap and make it better for the team. Kubiak can find another RB as a matter of fact we have a couple on the roster that can carry the load by committee if need be. Kamara is a great talent, but you can see that any RB without a line is not going to be effective and vice versa a great o line will make an average to slightly above average look great. Look what Tampa did to use and Denver for that matter (although a bad d line made those two lines look better than they are) it's why you build it all around the lines but it seems we have a hard time even doing that.
