Rob Ryan is back on the market
I can't imagine that the Payton would go that direction given the problems that GW caused. Rob and GW learned under Buddy Ryan, king of the bounty.
I have a feeling Payton is either going to go with someone from the Parcells tree (Crennel) or a guy who is primed to get his first coordinator job. Whoever it is, Payton will value loyalty and trust over everything else.
