The final "Monday Night Football" game of the 2021 NFL regular season was exactly what most expected it to be. The Steelers and Browns engaged in a cla sic grind-it-out AFC North battle with Pittsburgh earning a 26-14 win thanks to a strong defensive performance and a great outing from rookie Max Pircher Jersey running back Najee Harris.All the attention was on Ben Roethlisberger in this one, as the long-time Steelers quarterback played in what many believe was his final home game. Big Ben was prominently featured in Pittsburgh's game plan and earned the win, but even he admitted that it wasn't a pretty one."You know what, it's funny because it probably didn't go the way you wanted it other than the win," Roethlisberger said of the team's performance in a postgame interview with ESPN's Lisa Salters. "That's all that really matters. That's kinda been the story of my career. It's not always pretty, but we find a way."Indeed, Roethlisberger had his share of struggles during the contest, but he was matched by Browns quarterback Baker Mayfield on the other side of the field. In fact, when you break down the numbers, thetwo combined for one of the worst quarterback displays of the 2021 NFL season.WEEK 18 PICKS: | Ben Roethlisberger stats vs. BrownsRoethlisberger wasn't particularly bad against the Browns. He just wasn't particularly good either.The 39-year-old veteran wasn't able to get the ball downfield much a problem that has limited the Steelers' offense over the last two seasons so he had to settle for a lot of checkdowns. As a result, he racked up just 123 pa sing yards while completing 24 of 46 pa ses for a touchdown and Kurt Warner Jersey an interception.Roethlisberger averaged just 2.67 yards per pa sing attempt despite throwing the ball so much. How bad is that? His mark is the second-worst in NFL history for a quarterback to throw more than 40 pa sesbehind only Je se Palmer. Roethlisbergeris just the fourth player in NFL history to throw 40-plus times in a game and finish with a yards per attempt mark of le s than 3.YearPlayerTeamYards per attempt2003Je se PalmerGiants2.562022Ben RoethlisbergerSteelers2.672016Derek CarrRaiders2.852006Bruce GradkowskiBuccaneers2.9Incredibly, 34 of Roethlisberger's pa ses came before halftime yet he still failed to reach 100 yards on those attempts. That marked the first time that had happened in the last 40 years, per ESPN Stats Info.Ben Roethlisberger attempted 34 pa ses in the 1st half and had 96 pa s yards.He is the 1st player in the last 40 years with at least 30 pa s attempts and fewer than 100 pa s yards in a half, including playoffs. ESPN Stats Info (@ESPNStatsInfo) Roethlisberger also posted a pa ser rating of just56.2 during Sunday's game, whichmarks his 15th-worst rating in his 246 career starts.It's also his lowest since he posted a 37.8 in a five-interception game against the Jaguars in October of 2017.Interestingly, Roethlisberger's 6.5 yard average depth of target isn't the lowest of his 2021 season. Per PFF, Roethlisberger's lowest ADOT came in Week 15 vs. the Titans, with a 5.0 mark.So, while Roethlisberger got the win, he certainly had a rough outing, as he indicated. However, he arguably played better Los Angeles Rams Hats than Mayfield, who had one of his worst games as a pro.MORE: Baker Mayfield stats vs. SteelersMayfield completed his first pa s against the Steelers to Jarvis Landry. It went for 20 yards. After that, things got ugly.Each of Mayfield's next 10 pa ses fellincomplete, which marked the longest streak of incompletions since 2019, per . He had trouble getting the ball past the Steelers defensive line, which knocked down three pa ses, while his receivers logged a couple of drops. He also threw an interception during the Darious Williams Jersey streak where he didn't see David Njoku break open and tried to force it to Donovan Peoples-Jones.. defense with the first takeaway of the game! : on ESPN: NFL (@NFL) Mayfield would eventually snap out of it a bit, but he still completed just 42.1 percent of his pa ses against Pittsburgh. That's good for the 12th-worst completion percentage among starting quarterbacks this year and is the second-worst mark of Mayfield's NFL career. He also became the first quarterback since 2017 to have five pa ses batter down at the line of scrimmage while being sacked at last five times.Speaking of sacks, Mayfield was sacked nine times in this contest. That's tied for the most sacks in a single game this season with Justin Fields. The fault for that falls partially on Mayfield's offensive line specifically, right tackle James Hudson who allowed five pre sures and three sacks on Monday but Mayfield also should have released the ball quicker as well.MORE: The final stats on Mayfield don't look terrible. He completed 16 of 38 pa ses for 185 yards, two touchdowns and two interceptions. However,he logged just a 53.1 pa ser rating, the fourth-worst mark of his career, and averaged just 4.9 yards per pa s attempt. That wasbetter than Roethlisberger'stotal, but it wasn't enough to save the pa sers from making dubious history with their performances.On Monday night, Baker Mayfield and Ben Roethlisberger combined for 308 pa s yards on 84 attempts.Per , their 3.67 yards per attempt is the lowest combined rate in a game in NFL history, min. 80 attempts. ESPN Stats Info (@ESPNStatsInfo) Obviously, Mayfield was hurting.He has dealt with several injuries throughout the year, the most notable of which is a torn labrum in his non-throwing Los Angeles Rams Home Office shoulder. Still, it was a rocky outing, and that's what allowed Roethlisberger and the Steelers to keep the Browns at an arm's length for most of the evening.
