Agree partly, but not sure if I am misreading you or we disagree on one key point.
Coaches evaluate kids, not ratings. They need to be able to evaluate two kids and take the 3* over the 5*. They are not just evaluating the minor differences after the recruiting services generally rate kids. They shouldn’t pay attention to the rankings, tbh. That is for fans to worry about. The rankings tell us how they are doing because when multiple top staffs want a kid, they get ranked higher. But they do not tell coaches who to recruit. That would be the tail wagging the dog, so to speak. Also they need to evaluate fit for scheme and culture, which is its own issue.
Re the ‘08 class, in addition to awful evals, another issue was way too many kids never even played or hardlly played before leaving the program. Some injuries, some attitudes, some who knows why.
