I think he's way more talented than Brazill or Whalen and will pass them with a whole TC under his belt. I think he's a solid hold with huge upside.
I see this popular opinion a lot. That the benefit of a whole training camp will help him and it should still I see a hole in this theory. If the longer he practices/plays leads to him grasping the system better and becoming a better and a more trusted option in the passing game why was his playing time decreasing as the season went on in favor of the Brazil and Whalen? That's the hole I see in this theory. Out of these options he was the least familiar with the system last year so in theory the more he played and learned should have equated to more playing time, not less.
Both of the others were on the team and went through two TC's and all the meetings. Rogers saw none of this. His abilities as shown at the combine and against the Bengals are way better than those two. They were much more comfortable with the O while he was getting by on talent. Once he gets comfortable and trains with them through camp he will pass them. He was signed in September then dropped and signed again. He basically had no practice with Luck before being thrown into games. Not many are going to even play under those circumstances.
I think his point was more that there was downward trend at the end of the season, where you would expect to see an upward trend based on the assumptions in this situation. For a few weeks, he was playing quite a bit, then, at the end of the season, for no obvious reason, he was not.
Could just be small sample size issues, but to me, it's a valid question. As an owner, I'm tempted to sell to someone who might think his ascendance is right around the corner. I'm not sure I buy it.
