I don’t care about any of the nonsense with Cam Newton. Instead, take a look at his 2011 and 2012 stat lines:

His Y/A is actually higher this year (although his sack rate is a little worse), and his rushing yards per game and yards per carry are both slightly up. Obviously the biggest change is that Newton simply isn’t scoring very much — he’s on pace for just 21 touchdowns after scoring 35 last year. But touchdowns are more volatile than metrics like yards per attempt, and tend to rebound quickly when paired with a strong yards per attempt average. Compared to league average, Newton’s only slightly worse in NY/A and ANY/A than he was last year, and he’s still above-average in both statistics. Statistically, he looks fine.

But the eye test certainly says Newton is struggling. And some stats back that up, too. Newton ranks 25th in Total QBR, although he only ranked 17th in that metric a year ago. Perhaps more importantly, the Carolina offense has plummeted to 29th in points per drive so far in 2012 (while ranking 17th and 19th in drive success rate), after ranking 6th in points per drive (and 6th in yards and 5th in DSR) in 2011. So the offense has been quite a bit worse, and significantly worse when it comes to scoring. That sort of matches what the “eye test” tells me.

But as Aaron Schatz pointed out to me, there are some odd splits going on with Newton. Take a look at how Newton’s performed on pass attempts on 1st downs this year:
