The Baltimore Ravens had lost 21 consecutive games in which they trailed by double-digits before rallying from a 10-point deficit to defeat Tennessee on Wild Card Weekend. With his eighth career playoff road victory, coach John Harbaugh passed Tom Landry and Tom Coughlin for most in NFL history. The Ravens will hope to get their coach another when they visit the Buffalo Bills on Saturday in an AFC Divisional Round game in the 2021 NFL Playoffs. Kickoff from Bills Stadium is set for 8:15 p.m. ET.

Baltimore (12-5) defeated the Titans 20-13 last Sunday to improve its postseason winning percentage to .615 (16-10), which is second only to New England's .638 (37-21). While the Ravens have won six in a row, the Bills (14-3) are riding a seven-game winning streak after edging Indianapolis last weekend for their first playoff win since 1995. Buffalo is a 2.5-point favorite in the latest Bills vs. Ravens odds from William Hill Sportsbook, while the over-under for total points scored is 49.5. Before locking in any Ravens vs. Bills picks or NFL predictions, see what SportsLine's resident Baltimore expert, Mike Tierney, has to say.

Why the Bills can cover

Buffalo was a dangerous team during the regular season, as it finished second in total offense (396.4 yards) and scoring (31.3 points) while ranking third in passing (288.8 yards). Quarterback Josh Allen registered eight 300-yard performances and threw two or more touchdown passes on 13 occasions. The 24-year-old was just as effective against the Colts last weekend, throwing for 324 yards and two TDs while running for a team-high 54 yards and another score. 

Allen was fourth in the league in completion percentage (69.2), fifth in yards (4,544), fifth in TD tosses (37), and sixth in yards per game (284) while leading the Bills with eight rushing scores.

Why the Ravens can cover

Baltimore scored both of its touchdowns against Tennessee on the ground, with quarterback Lamar Jackson recording one and rookie J.K. Dobbins notching the other. The 22-year-old Dobbins has rushed for a score in seven consecutive contests and can tie Maurice Jones-Drew (2006) for the longest such streak ever by a rookie with a TD on Saturday. Dobbins has registered a total of eight touchdowns during his streak.

The Ravens, who are 6-3 in the all-time series against Buffalo and have won three straight meetings, also came up big defensively versus the Titans last weekend. They had a 401-209 advantage in total yards and outgained Tennessee 236-51 on the ground, holding two-time reigning NFL rushing leader Derrick Henry to a season-low 40 yards.

During the regular season, Baltimore ranked eighth in the league against the run (108.8 yards), seventh in total defense (329.8), sixth against the pass (221) and second in points allowed (18.9).
