Kap sucks

It's simple, really (and what PFF and FO is totally different, btw). Passing yards per game are largely, but not entirely, a function of the number of passes thrown - they tell you nothing qualitative other than that the team likes to throw or else is often behind in games (and is forced to throw). Completion % is a useful number. But those are just two, context-free numbers. What FO does is look at the result of a play against all other plays like it, and adjusts for the quality of the defense (in fact, SF's is adjusted quite a bit as they've played the 7th-toughest schedule in terms of defenses faced - think AZ and SEAT twice, e.g.). So take the example of completion percentage, and use some simple numbers. Team A's QB goes 5-10 for 35 yards. Team B goes 7-10 for 49 yards. Team B's guy is better, right? Well what if I told you that all 5 of the Team A's completions went for first downs and he was playing against the best pass D in football. Meanwhile Team B's QB completed his first pass for 39 yards, but the rest of the way went 6-9 for 9 yards and no first downs. And did this against an average defense - Would you still view the numbers the same way? Of course not. Well that's really all FO does, and their rankings seem to make some sense - do any of these teams really look out of place in the top 5 for passing?1. Denver2. San Diego3. New Orleans4. Seattle5.
