‘Case Keenum had more turnovers last week than he had incomplete passes on Saturday. Against the Broncos, the Bills backup quarterback was lethal, completing 16 of 18 passes for 192 yards and a touchdown. Unlike in the Bills’ preseason debut, Keenum had a chance to work with plenty of starters, and he took advantage of the opportunity. While Barkley also had a strong outing, it’s clear Keenum is the favorite to win the backup job as the team gets ready for the regular season.’
