This is kind of confusing. Did ESPN just make up their own QBR or did CNNSI? I am just wondering what is the real (official) QBR is. I found this list in the below link
The No. 1 ranking takes on more gravitas when you look at the list of contemporary legends staring up at him on the Real Quarterback Rating leaderboard.
Top 8 Real QB Rating (through Week 7)
• No. 1 -- Griffin and the Redskins (99.9)
• No. 2 -- Peyton Manning and the Broncos (97.3)
• No. 3 -- Aaron Rodgers and the Packers (97.2)
• No. 4 -- Tom Brady and the Patriots (93.2)
• No. 5 -- Matt Ryan and the Falcons (92.3)
• No. 6 -- Drew Brees and the Saints (91.9)
• No. 7 -- Ben Roethlisberger and the Steelers (91.2)
