And?
Of those ten teams, Seattle was second fewest in attempts. Of all the teams with a YPA of greater than 7.0, only SF, Sea, and Car have fewer than 500 attempted passes. Nobody is saying that Wilson wasn't efficient. He most certainly was. IMO, part of the reason for his efficiency was the small number of attempts and the requirement for opposing defenses to focus on the running game . It just so happens that the same three teams are 1, 2, and 3 in points allowed. Preventing the other team from scoring means you don't play from behind. You can stick to the running game. You can pick your spots. You can be more efficient passing the football.
When you have the lead and can run the ball, you force the other team to try to stop you and get the ball back. That opens up opportunities for big chunk plays (which helps YPA). If they don't work, you punt and rely on your crushing defense to stop the other team again. And so it goes. It all works together (as long as you have all the pieces).
The teams above 7.0 YPA are:
Phi, Sea, Den, SD, GB, NO, SF, Chi, Arz, Cin, Pit, Det, Dal, Car
of those, these are also in the top 10 in passing yards:
Den, NO, Det, SD, Chi, GB, Cin, Phi, Pit, Arz, Dal
Those are the teams that combined efficiency and quantity. IMO, there are only 3 "surprises" on the list:
1. NE was not on it. This has been discussed at length, and I believe that NE was hampered by their receivers. (team sport, remember)
2. Ariz is on the list. Carson Palmer had a better year in some respects than I thought. INTs were the problem.
3. Cin is on the list. IMO, Dalton (and maybe Cutler) is the opposite of Brady in this analysis. He is elevated by his receivers.
The rest of the QBs are Manning, Brees, Stafford, Rivers, Cutler, Rodgers, Foles, Roethlisberger, and Romo.
Those are all QBs that I rank above Wilson, Kaep, and Newton. BTW, all of those teams threw more TD passes than Seattle also.
