Serving as Buffalo’s full-time right tackle in 2016, Mills started all 16 games and graded as the league’s No. 64 offensive tackle among 78 qualifiers, per Pro Football Focus. The Bills originally signed Mills off Detroit’s practice squad in October 2015, and he’s become a productive player in Buffalo. A former fifth-round pick, Mills has 50 career starts under his belt, all of those coming with the Bills and the Bears (with whom Mills began his NFL tenure).
The Bills’ offensive line, which paved the way for the league’s No. 1 DVOA-rated rushing attack, should return the same five members from left-to-right: Cordy Glenn, Richie Incognito, Eric Wood, John Miller, and Mills.
