I can't disagree. I would probably place Milroe behind all of them, including McElroy even with his limited physical tools.
Really makes you wonder what on earth happened over the last 3-4 years that we find ourselves in this QB wasteland relative to what we've had in the past.
Clearly we have done a poor job in recruiting and/or development.
What happened?
QB is a hard position to project from HS to college, especially if the college is in the SEC. So some of the current issue isn't a function of recruiting -- Ty Simpson was a 5-star recruit. Milroe was a 4. I'm not 100% sure, but I think Tyler Buchner was also a 5. I know that several posters have said that we wanted him coming out of high school.
Simpson has struggled with just letting the game flow. Milroe has struggled with decision-making and short to medium passing accuracy. Buchner just didn't have it.
Development has definitely been an issue, pointing a finger directly at O'Brien. I don't think we had any QB get better under him. Bryce Young might have regressed from his Heisman sophomore season to his junior year.
I'd also not overlook the OL. It's hard for any QB to go through his reads if there's a DL in his grill before he gets his feet set.
OL is also hard to project from HS to college. But we had 5 and high 4 stars all over the place, and after 2020 (under Landon Dickerson's leadership) haven't put together anything approaching coherence. Some bad luck recruiting, but Marrone had a lot to do with the lack of development. Even with the difficulty in projecting performance, we should have been better than we were.
Short answer: I think the core cause of our QB problems is lack of development of both QBs and OL, resting with O'Brien and Marrone. Some misses in recruiting aggravated the issue, but they weren't the primary cause.
