Well boys, I live in Buffalo, and I haven't heard anything about this. The trade has been on the table for weeks (maybe months), and the last we heard around here was that the Bills were perfectly happy taking Henry into training camp as a backup (I'm sure it was just a negotiating tactic).
One theory around here was that since his value dropped so much in the offseason, they were going to hold on to him until preseason when that starting RB gets injured (which RB, I don't know, but there is always somebody), and then they could deal him to a team that was desperate.
Personally, I'd like to see them get Shelton and exchange their 2nd round pick for Arizona's 1st. I'm not overrating Henry, in fact, I was never really that fond of him, but he's the last talent left on FA, he's a proven 1400-1500 yrd RB, and the RB pool in the draft is relatively lackluster.
Anyway, enough out of me.
