Fourth-year tackle Jeff Allen has returned to the Chiefs' starting lineup in the past two games, moving Eric Fisher to left tackle. Allen, who started in 27 games in his first two years in the NFL, played in just one game in 2014 but has been a refreshing part of the Chief's success on the ground in recent weeks.
Despite the loss of running back Jamaal Charles, Allen has been able to help Kansas City continue in his path with backup RB Charcandrick West. Also, in Allen's 133 snaps so far, he has yet to allow a sack on QB Alex Smith, who has been sacked 28 times.
Miller will give him his biggest challenge yet, and should Allen give up any pressure, it could be disastrous for Kansas City, who had five turnovers against the Broncos in Week 2.
