I don't think Hurts needs to make any huge leaps forward, it's just improvement in a few key areas that could be huge. I mean, the way some people are talking (not you) you'd think he didn't throw for 2780 yards and 23 TDs. Statistically speaking, Jacob Eason as a passer was worse in pretty much every statistical category. Less yards, 16/8 TD to INT ratio compared to 23/9, 55.1 completion percentage compared to 62.8, 120 rating compared to 139. I don't think anyone is calling Jacob a bad passer either, oh yeah Hurts faced tougher defenses to.
So, I think once he reads defenses a little better, his overall vision improves, and he has a little more touch? Just pretty simple progression for a freshman quarterback, he could be scary good. I just hope he doesn't form ingrained bad habits or regress.
