I do not dispute his perspective or value and there is no evidence that I ever have. But I do not agree with his assessment and I watched Herbert for multiple years, under multiple offensive schemes, in both college and the pros. My original, and continuing contention, is that he did not progress under the Mario offense. Now we can fight about what progression is or should be, and he obviously grew and developed as most do as they age, but I don't think anyone truly argues that Mario got anywhere close to maximizing the college level Herbert. Herbert's depth of target and completion percentage both dropped. That is quite unusual, in fact offenses usually reduce depth of target attempt and get an increase in both completion percentage and QB rating (see Can Newton at Carolina).
Brooklynn disagrees. He made what he termed a statistical argument, then refused to recognize statistics that did not support that argument. He even provided stats from 1983-84 Bernie at Miami and 2017 plus Herbert at Miami. Really, 30+ years apart, that's apples to apples? Does anyone think the game is the same? Then, clearly, Brooklynn got mad.
If your rationale is that I cannot disagree with a person, because of who he might be, then that is your rationale. It does not make it my reality.
This all started with a discussion of Mario's offensive history, particularly QB development. Simply put, QB recruiting and NFL drafting of those QBs will tell us what Mario brings to the table in this regard. Herbert was a gift. He was not even a Mario recruit; Mario inherited him in a pre Portal world. What has Mario done otherwise to attract and develop the position? Again, time will tell.
