A guy to keep an eye on at DT in the Bills future is Arik Armstead.   Had an injury plagued year and a big production drop-off so I wouldn't be totally shocked if the 49ers cut bait rather than pay his base salary.   He met a girl in Buffalo after a 49ers/Bills game and subsequently married into a family of Bills fans.  If he changes teams in the next 10-11 months I could see him coming to the Bills.
