The best thing the Saints could do by Alvin Kamara is to trade him to a contender.
I think it's funny that the thread title is framed as if the Saints would be doing Kamara a favor by trading him when the man himself has said every time it's been brought up that he wants to finish his career here. He showed he can still be the running back he was coming out of college earlier this season when we were healthy. Even in our last few games there's been flashes of that despite our lack of passing threat and the injured o-line, but we've also started going sideways on offense a lot more which I imagine has to do with that banged up interior line. I do understand the money needs to make sense for both parties but personally I hope the organization can make it work.
I agree that ideally we'd have another RB to split carries with him, Jamaal Williams hasn't worked out exactly like we had hoped. Miller might be able to take that role if he can stay healthy but I think we'll draft another RB this offseason as well.
