Yeah, I don't think it's so much that he's regressed, that he rushed back probably a bit too soon. He got hurt almost what, one year ago to the day today? What made him really good last year was his pocket mobility, and ability to improvise and throw on the run. I think he's probably tentative on the knee, afraid of blowing it out again, so he's probably more conscious of anyone or anything around his legs.
For comparison, take a look at Brady in 2009, when he came back from the injury. It was probably his worst season (besides 2013, which had it's own set of problems) going back to 2006. He was getting rid of the ball so quickly that year because of the fear of getting hit that he only got sacked 16 times (his previous low was 21 times in 2007, but before that, it was 26), and then in the years after that, he was sacked 25,32, 27 and 40 times over the next 4 years. He threw more picks in 2009 than in any season from 2005 until now.
I think that's all it is with Wentz. I think he's gotten better even as this season has gone on, and if he stays healthy and comes back strong next year, he'll be right back to where he was.
But you're definitely right, there's only one AP. What was the year he blew out his knee late in the season (the first time?) and made it back in time to start opening day the following season?
