RB Kareem Hunt visiting the Saints tonight; Saints also working out LB Anthony Barr

I don't think he is done physically, I'm just parroting what all the talking heads are saying about NFL trends with running backs.
I think it's more nuanced than that. It's probably the amount of years and guarantees that is holding him up from signing with someone. Teams probably want to give him a 1 or 2 year deal and he wants 3-4 maybe?
