They're always a risk, no doubt.
The RB market is an interesting one. Numbers are coming down, not going up, and teams paying big money to running backs are looking to get out of those contracts. In my opinion, there was no way Peterson was staying in Minnesota under his ridiculous deal before this incident, no I see no chance he stays.
Given that change in contracts, it's hard for me to peg exactly where the RB market truly is.
No, I value Murray and hope he returns, but it has to be at a price that works for both sides.
On a side note, I've noticed a focus from Murray on maximizing his earnings potential, even during his rookie year. My brother frequents signing events and has told me that Murray is a regular at those events, even back in his rookie year.
I think he's a sharp guy who knows about maximizing his earnings potential and negotiations with he and his agent won't be easy.
