So I was looking more on ESPN regarding that QBR.  I was wondering what his QBR for SBXL was, because that would really argue the stat, given the clutch plays he made.
http://espn.go.com/nfl/qbr/_/year/0/type/alltime-gameI did find these games by Ben.  Starting with the 2006 season, apparently.
I think they changed it up, given the stupidity of Batches game being #1.
