Manuel's 8.4 QBR is NFL's worst in Week 3

Watching Monday's 9 a.m. live "SportsCenter," this note from host Hannah Storm caught our attention at the top of the program:

Yesterday was a huge day for quarterbacks throughout the NFL. Qualified quarterbacks combined to average a QBR of 71. That's the highest in a single week since ESPN began tracking that stat back in 2006.

Total QBR, an advanced statistic developed by ESPN, falls on a scale of 0 to 100 and uses historical and situational data to evaluate quarterbacks.

With such a successful weekend for quarterbacks around the NFL, it also caught our eye that Buffalo Bills quarterback EJ Manuel currently has the lowest Total QBR in Week 3, prior to Monday Night Football.

In fact, Manuel's 8.4 Total QBR in Sunday's 22-10 loss to the San Diego Chargers is the second-lowest Total QBR in any game this season. Only Chad Henne's 4.1 Total QBR in Week 2 was worse.

Further, Manuel's 8.4 Total QBR was the second-lowest of his career. In a Week 14 loss to the Tampa Bay Buccaneers last season, Manuel posted a 3.8 Total QBR.

In three games this season, Manuel has a 31.1 Total QBR. Only Minnesota's Matt Cassel, Miami's Ryan Tannehill and Henne have lower Total QBRs.
