I'd love to be an observer in one of these situations once.
I can't figure out what would take so long. Nix makes an offer, Williams either wants to play for Buffalo or he does not. If he does they negotiate contract terms which shouldn't take a large amount of time. If he does not he says no thank you and moves on. Seems like that's how it was for a lot of the other FAs, what's the difference here?
Unless he is waiting for other offers to drive the Bills price higher, or using the Bills offer to drive someone elses offer higher?
Like I said, I'd love to see how one of these situations works from the inside once.
