		Right tackle
One tackle spot is set in Buffalo, with 
Cordy Glenn signing 
a five-year, $65 million extension this week. But the other tackle spot is a big question mark. The biggest problem is that 2014 second-round pick 
Cyrus Kouandjio has never developed. The Bills somewhat made up for that failure by finding a passable right tackle, 
Seantrel Henderson, in the seventh round that same year. But Henderson missed the last five games of last season battling Crohn's disease, and he's likely to miss at least part of the 2016 season trying to get healthy and back to his playing weight. That leaves 
Jordan Mills, the 
Chicago Bears' castoff who passed Kouandjio on the depth chart to start last December. Mills was not very good with the Bears, which is why they cut him after only two years. Buffalo didn't draft a single lineman this year; the best remaining free-agent tackle is probably Khalif Barnes, who is 34 and started only one game for Oakland last season.
