I think one of the hardest things to evaluate and teach a QB is pocket awareness. You watch the great ones in the NFL, they are not all speed demons, but they know how to slide in the pocket, when to leak out of the pocket and when to tuck and run. Its nearly as important a skill as throwing accurately. Banks and Tate were so good in the pocket. CJ was as well.
Starting with Stanley, this skill has gotten worse and worse. Hill was awful at this and Petras worse.
We need a OC that can also develop QBs. And I agree that QB recruitment has not been good. We get the same kid: marginal 4 star recruit that lit things up in high school as a spread QB but does not have the natural skills or athleticism to make it at the collegiate level. We need to do better.
I agree that Petra wasn't great with pocket awareness, but I think Hill is the worst yet. There were probably half a dozen sacks (multiple resulting in fumbles) that were entirely on him, not the OL.
Stanley was a solid athlete (holds numerous testing records, especially strength-related, for Iowa QBs), but he wasn't great in the pocket, and he didn't have that natural wiggle that CJ or even Rudock had. He did progress while he was here. I am not sure why, but Resar kind of reminds me of Stanley in the limited highlights I watched, but obviously with better straight speed (10.6 is legit). He doesn't necessarily seem shifty. His stats aren't eye-popping, but neither were Stanley's, and I don't know anything about his system or the level of competition.
Our QBs have been downhill since Greg Davis left. Say what you will about his offensive design, but he seemed capable of identifying and developing decent QBs. Since he left, the QB room has been a struggle.
