‘That last sentence I just wrote about Miller also applies to Mills, who has been with the Bills for the better part of four seasons after two years with the Bears, as well as the Cowboys and Lions practice squads. Like Miller, Mills’ tenure on the right side of the Bills’ line was uneven. The organization felt he played well enough in 2015 and 2016 to receive a two-year contract extension, but the last two years have been too inconsistent for the team to feel they need to bring him back. They should look to upgrade at the spot, but not close the door on Mills returning on a veteran-minimum type of deal for depth purposes.’
