With the young QBs, either rookies this year or last, Derek Carr is the one tearing it up so far in QB Rating. Having Amari Cooper no doubt has helped! Looking at QB ranking, he is now at #6. Mariota is currently #9. Then it's Bridgewater at #23, Bortles at #26, and Winston at #27. If you prefer looking at Yards per Attempt, Mariota leads this group at #7. Carr drops to #10, Winston jumps to #11, Bridgewater is at #20, and Bortles is at #28. Or if you like plain old Yards per Game, ya get a very different picture. Carr is at #13, Bortles jumps to #14, Mariota drops to #17, Winston is at #24, and Bridgewater is at #29. Percentage of Completions shows Mariota at #10, Carr at #15, Bridgewater at #17, Winston at #27, and Bortles at #30. http://espn.go.com/nfl/statistics/player/_/stat/passing/sort/quarterbackRating
