Sadly, I moved Pryor in a deal this week to get Cam. To respond to the person above who said you won't get full value for him because non-Pryor owners will discount him as a fluke, that's certainly true. But you'll definitely get more for him now than you could've two months ago. While I'm a huge fan and love his story, there are reasons to deal him now. Mainly, that his 'pop' in value has already occurred. He went from a waiver-wire or very late round draft pick (I got him in the 17th round in a dynasty start up in August), to borderline QB1/2. If the draft were today, he'd be a 10-15 QB pick, probably in the top 10 rounds in a dynasty start up. If you can cash in on that pop in value from essentially no-value to mid-round value, that's a nice ROI, even if you don't get the full value that you think you should.
If you hold him hoping that his perceived value increases even more, you're gambling that he continues to improve on the trajectory that he's been on since the end of last year. Instead, I think his big jump as a passer already occurred, and any improvements going forward will be incremental. Accordingly, his big jump in value already occurred, and any improved value going forward will be incremental.
While it's easy to say he's improving and expect him to get better next year, and the year after... I think in reality his upside is capped by the organization which has been unable to put together a decent line over a number of years. The reasons I like Pryor/the Raiders are the same reasons that I don't think he'll continue to improve (more than incrementally) - namely lackluster talent around him and a dysfunctional management. Those underdog aspects make him fun to root for, but, I think they'll remain underdogs for a while. Turmoil, coaching changes, inferior coaching, inferior line play... these all seem like constants, to some extent, even though it's been nice to see the Raiders regain a bit of respectability.
And then there's the rushing -- his speed is top notch, his size is great, but other than that first Indy game there have been very few runs that were really impressive. He doesn't get the goal line plunges like Cam despite being almost the same size. He also seems to run only on the edges when contain breaks down. I don't see him running wild through the middle of the field like Cam and Kaep. Even Russel Wilson shows more ability to run and juke, especially in the open field, whereas Pryor remains mostly near the sidelines, gets the yards available until the angle catches up, and then steps out.
