Let’s have a look at how the quarterbacks of the AFC South are faring in passer rating and QBR, shall we?
Passer rating maxes out at 158.3; QBR goes to 100. At this QBR page, you can sort numbers for the season or by week.
For a game, QBR can be interpreted as a percentile, so a score of 80 means a QB’s performance was better than 80 percent of all QB games.
A reminder on Total QBR: It’s a quarterback rating that takes into account all of a QB’s significant contributions (passing, rushing, sacks, fumbles, penalties) to his team’s scoring and winning and summarizes them into one number on a 0-100 scale, where 50 is average. Since 2008, the team with the higher QBR has won 86 percent of the time.
Luck's the first rookie to lead in QBR since 2008, when Atlanta's Matt Ryan led the league for multiple weeks.
Ben Roethlisberger (80.4) and Ryan (80) trail Luck and are the lone regulars at quarterback who have QBRs of 80 or above.
