I don't see him having much of a market, he still makes sense in Buffalo because of what he brings off the field and he can mentor the young guys. I fully expect him to look noticeably slower than last year, he is old for a WR and has a big body.
I'm in the camp that thinks he signs here and does so very soon. This is an easy roster for him to make, they need his personality even more than they need him playing 20+ snaps.
