'Mills, 26, started every game last season for the Bills, taking 97 percent of the offensive snaps. Although he has plenty of experience, with 50 career starts, he was viewed as the weak link on the Bills' offensive line in 2016. The analytics website Pro Football Focus graded Mills 64th out of 78 qualifying offensive tackles, charging him with nine sacks, six quarterback hits and 44 hurries. The Bills appeared on the verge of handing the right tackle job over to Seantrel Henderson midway through the season, until he was suspended for a second time.'
