When you look a the 21-31 yard passes he has a 60.7 QBR with 4 of 13 with 1 TD and 1 pick.
So for passes over 21 yards he is 8 for 20 (40%) 2 Td's and 1 pick. That equates to a QBR of 100
Still impressive with what he has to work with but hardly the story reported by espn. Do they ever get anything right?
