The Bills used a low-round tender on Mills that will run them $1,671,000 for the 2016 season. This designation gave them the right of first refusal on any contract offer he received, but wouldn’t have included any compensation had they elected to not match an offer.
Mills, 25, is a former fifth round pick of the Bears back in 2013. He spent two years in Chicago before he was released during roster cuts and later claimed off of waivers by the Cowboys.
Dallas elected to waive him after just a week with the team, but he managed to sign on to the Lions’ practice squad midseason. The Bills later signed him off of the Lions’ practice squad.
In 2015, Mills appeared 10 games and was rated by Pro Football Focus as the No. 57 offensive tackle out of 77 qualifying players.
