‘Key matchup: Bills O-line vs. Broncos D-line. Allen’s elusiveness combined with a line that’s featured the same five starters for all but two games this season led to Buffalo allowing a league-low 14 sacks — the fewest since Indianapolis allowed 13 in 2009. Meantime, the Broncos led the NFL with a single-season best 63 sacks, including 12 over their final two outings.’
