mistertim Posted October 9, 2007 Share Posted October 9, 2007 I was checking out the NFL QB leaders on nfl.com and noticed something sort of odd. Philip Rivers had a QB rating of 151.4 with 13/18 completions, 270 yards, 2 TDs and no INTs. Jason Campbell had a QB rating of 125.3 with 23/29 completions, 248 yards, 2 TDs and no INTs. His comp% was actually better than Rivers and yet he had a much lower QB rating. Can 22 more yards really make THAT much of a difference in QB rating? I don't know all the aspects that go into QB rating, and I know this isn't that important but I was wondering if someone in the know about this sort of thing could shed some light on what I'm missing. :logo: Link to comment Share on other sites More sharing options...
Enter Apotheosis Posted October 9, 2007 Share Posted October 9, 2007 yards per attempt also figures in and Rivers CLEARLY had a higher YPA than Campbell. Link to comment Share on other sites More sharing options...
Coach Williams Posted October 9, 2007 Share Posted October 9, 2007 Yes, they is a minimum # of yards PER pass needed to achieve a perfect QBR of 158.3 you also need a ratio of TD's to passes to be higher than a certain # also... I wish I had the chart I am picturing Link to comment Share on other sites More sharing options...

#98QBKiller Posted October 9, 2007 Share Posted October 9, 2007 Here's how wikipedia shows the formula: Link: http://en.wikipedia.org/wiki/Passer_rating NFL and CFL Passer rating is determined by four statistical components, each of which is computed as a number between zero and 2.375. The benchmarks for these statistics are based on historical averages. If any of the components are less than zero, they are reckoned as zero; if any are over 2.375, they are reckoned as 2.375. The component for completion percentage, C, is calculated as: The component for yards per attempt, Y, is calculated as: The component for touchdowns per attempt, T, is calculated as: The component for interceptions per attempt, I, is calculated as: The four components are then added, divided by 6, and multiplied by 100. Thus, the formula for passer rating can be given as: . The CFL appears to use the same formula as the NFL [edit] Perfect rating Since each component of passer rating can be at most 2.375, the maximum passer rating is . A perfect passer rating therefore comprises: a completion percentage of at least 77.5%: at least 12.5 yards per attempt: at least .11875 touchdowns per attempt, or at most 8.42 attempts per touchdown: and zero interceptions: Link to comment Share on other sites More sharing options...
chrisc0015 Posted October 9, 2007 Share Posted October 9, 2007 Aikman's Efficiency Rating is a much more telling stat... Link to comment Share on other sites More sharing options...
mistertim Posted October 9, 2007 Author Share Posted October 9, 2007 yards per attempt also figures in and Rivers CLEARLY had a higher YPA than Campbell. Ok that makes sense. I was thinking that may be included but then I remembered that Brunell had a high rating last year without many long throws but then I also remembered that YPA includes YAC from the receiver.

SkinsManNJ Posted October 9, 2007 Share Posted October 9, 2007 Can't they come up with a better way to calcuulate the QB rating? Not all football fans are good at algebra or higher mathmatics. Link to comment Share on other sites More sharing options...
