In 2015, Carson Palmer finished first in ANY/A, as did his Arizona Cardinals. It was a magnificent passing season for Palmer, who was 36 years old last season. In the offseason, I noted that it was a big outlier, but there were a couple of ways you could interpret the data:
If you’re a Palmer fan, the results here can both show how much of an outlier Palmer is, but also might be considered inspiring. Peyton Manning was really good at age 36 and then historic at age 37; Gannon and Steve Young had great years at 36, and then were even better at age 37. The same goes (with a slightly lower baseline) for John Elway, Kurt Warner, and Tom Brady. Supporting cast is undoubtedly a big part of this, and Palmer seems to be playing with one of the best ones. The wildcard in the room is how much his meltdown in the NFC Championship Game impacts him mentally.
The general rule of thumb, I think, for an older quarterback is to project them to be OK until they aren’t. What does that mean? Well, I think of Adam Harstad’s mortality tables. Just because a quarterback is old doesn’t mean he’s going to have a 5 or 10% decline: guys like Manning, Gannon, Young, Elway, Warner, Brady, and Brees are examples of that. But once that decline hits, it’s often severe and permanent. For now, though, Palmer is still one of the rare quarterbacks who had his best season at age 36.
Well, we have our answer. While teams like the Texans, Panters, and Jets have suffered notable declines in the passing game, all three teams are dwarfed by the decline in pass efficiency endured by the Cardinals this season: [click to continue…]
