Explain to me ESPN's QBR

[USBHawk]

JT Barret: 17/29 226 7.8 1 1 69.3
Alex Hornibrook: 16/28 214 7.6 1 1 24.5

So if Hornibrook completes one more pass for 12 yards, his QBR goes up by 45 points? Makes no sense.

edit: I suppose the 92 yards rushing vs -34 has something to do with it.

I believe there is a success and credit element in the rating that can make things tricky. For example, if a QB has a pass for 12 yards and 3rd and 15, that isn't a successful play. But a 8 yard pass on 3rd and 7 is successful. The credit part is if a QB throws a screen and the RB gains 50 YAC, the QB doesn't get a lot of credit because the RB did most of the work. Where if the QB hits a 35 yard pass that traveled 35 yards in the air, he's going to get a lot of credit for those yards.

Makes sense. Thanks.

Yeah, if you google "What is QBR" you can find ESPN's description.

It's about as clear and concise as the online/software EULA's we're always supposed to read.

I can't imagine how it's actually calculated. Is somebody watching every play to manually determine "credit", "clutch", etc?

weird. Thought Hornibrook outplayed Barrett most of game
