Pro Football Focus Grades: Jets Vs. Miami. in NY Jets Forum Posted October 8, 2015 What I dont understand is how does the NFL give Fitzpatrick a 91 QBR yet PFF gives Fitz a negative score? Its funny because Fitz game wasnt really great yet if you were to solely look at the QBR stats it would look like Fitz had the 2nd best QB peformance of all QB's on Sunday. I guess the more accurate conclusion would be somewhere in the middle. Guess it depends on the exact criteria ... I presume PFF is more situational? In QBR terms, missing on a dump off pass would be the same as missing on a Hail Mary, as both simply count as incompletions. But if my QB is missing on dump off passes regularly, I'd be a lot more worried than if he's missing on Hail Marys. Similarly you can get an OK QBR while regularly throwing for 8 yards on 3rd and 10. Nice stats, but the result isn't what you want.
