Browns’ Joe Flacco has biggest fourth quarter of any QB this NFL season, plus 13 other wild stats from Week 15

Joe Flacco is officially back. 

After spending the first 11 weeks of the season watching football on his mom’s couch, Flacco has returned with a vengeance. The Browns QB made his third start of the season on Sunday and after struggling through the first three quarters with three interceptions, Flacco went off in the fourth quarter. 

The 38-year-old went 11 of 13 for 212 yards and a TD to help propel the Browns to a 20-17 win over the Bears. If you’re wondering how impressive it is to throw for 212 yards in one quarter, we’ll be covering that below as we go over 14 of the most interesting stats of Week 15. 

If you’re new here, I get an email every week from our CBS Sports research department, and that email always includes some amazingly wild stats about the games that were just played. 

With that in mind, here are 14 of the craziest stats from Week 15: 

1. Flacco’s magical fourth quarter. The Browns QB threw for 212 yards in the fourth quarter against the Bears, which is the most by any Browns QB since at least 1991 and the most by any player in the fourth quarter of any NFL game this year. Flacco also became the first Browns QB to throw for at least 300 yards in back-to-back wins since Brian Sipe in 1980. 
2. Christian McCaffrey is a scoring machine. With three touchdowns against the Cardinals, McCaffrey now has 30 touchdowns in his first 25 games with the 49ers, which is the second most in NFL history for a player through his first 25 games with a team. Only Gale Sayers, who had 31 with the Bears, had more. McCaffrey scored a total of seven touchdowns this season against the Cardinals, which ties the most by one player against a single team in a single season in the Super Bowl era.
3. From undrafted to awesome. With two rushing touchdowns on Sunday, Raheem Mostert now has 18 for the season, which is tied for the third most by any undrafted player in NFL history. The two scores also gave him 20 total touchdowns for the season, which is a single-season franchise record for the Dolphins. 
4. Dolphins dominant defense. The Dolphins surrendered just four yards to the Jets during the first half on Sunday, which is the fewest yards that any team has given up in a first half since December 2015 when the Broncos…
