Joe Flacco produced a 0.4 Total QBR in Sunday's loss to the Broncos, which was tied for the second-lowest this season.
Who has the worst QBR in a single game this season? That also belongs to Flacco, who posted a 0.3 QBR against the Texans in Week 7.
Flacco also joined Mark Sanchez and John Skelton as the only players with multiple sub-1.0 QBR games over the past five seasons. If you're Flacco, those aren't the names you want to be linked to as a quarterback.
What made Flacco's performance one of the worst of the season was his struggles on third down (he converted 1-of-11 third-down pass attempts into first downs) and his momentum-crushing interception late in the first half. Trailing 10-0 in the second quarter, Flacco was picked off on an out route at the Broncos 2-yard line that was returned for a touchdown.
According to ESPN Stats & Information, that cost the Ravens 11.9 expected points when taking into account Baltimore’s lost goal-to-go opportunity and the resulting touchdown for the Broncos. That is the second-worst single play in terms of expected points added (EPA) over the past five seasons.
The only play worse was the interception thrown by Arizona’s Kurt Warner that was returned for a touchdown in Super Bowl XLIII against the Steelers. In both instances, the throws by Flacco and Warner were intended for Anquan Boldin.
