He had a pretty remarkable season. I actually think it is more likely he regresses. That is why losing to the Packers hurt so bad. They were riding a wave, Prescott included.
I think he could get better as a QB -- and have that be a positive reflection on his long term viability here -- but still put up worse numbers. I mean, 23 TDs to 4 INTs is just not a sustainable ratio. What, is he gonna throw 35 TDs and 6 INTs next year? Unlikely.
I would expect in a full season from him this year to see upticks in passing yardage and touchdowns -- maybe 3800-4200 yards as opposed to 3600, and 25-28 TDs instead of 23. But I also expect his completion percentage to fall and his INTs to jump to over 10.
I also expect our record to slide. I would expect a team that is just as good as last year's to finish more like 10-6. We caught a lot of breaks last year and it won't run all our way again. We also have a harder schedule.
Depending on what happens with the defense -- if Jaylon Smith is a Pro Bowl caliber player, if we can find a stud pass rusher and patch secondary holes with starting caliber rookies in the draft, if we see second year improvement from Anthony Brown and Malik Collins, if we get similar or improved production from Sean Lee, Tyrone Crawford, Byron Jones, etc, we could be significantly better on defense, and thus we could be a significantly better team. Dez Bryant being fully healthy all year would go a long way too.
So we could be a better team than last year. As it stands right now, we probably are not.
