2018: Ravens vs. Bills, W 47-3
The 2018 season was the one in which the Ravens finally flipped their no-postseason page and turned it into the start of a three-year run reaching the playoffs from that year through 2020.
Things couldn't have started better for Flacco in his last year as the starting quarterback of the Ravens before opening the door to a young Lamar Jackson later in the season.
The Ravens cooked Buffalo and Flacco was the main perpetrator of the crime throwing three touchdown passes to John Brown, Michael Crabtree, and Willie Snead before the clock hit 12:00 into the third quarter to put the Ravens up 33-0 there.
The team later scored 14 more points thanks to a couple of rushing touchdowns (one by Javorius Allen, one by Kenneth Dixon) near the goal line, with Stephen Hauschka kicking a 35 field goal in because Justin Tucker wasn't even needed anymore. So dominant was the Flock.
