I'm not running with the "ruining quarterbacks" narrative.
Herbert was still drafted #6 overall so I hate that narrative.
First off, Mario himself called TVD the best QB in the country. Now I know that was new coach hype. But everybody in America had very high expectations from TVD.
But Mario is absolutely not doing TVD any favors. If he could look like a star in a gimmicky offense, I don't care. Why not keep running that "gimmicky" offense until you get your guys and systems in place? Why this wholesale complex offensive system change without knowing what you're going to get when we all know TVD could thrive in a different system?
He blundered with TVD and this offense. At best he did not play to TVDs strengths and at worst he absolutely ruined a first round QB. Neither is very confidence inspiring and definitely doesn't promote "patience".
You throw TVD under the bus all you want but this TVD we're seeing this year is not the same one we saw last year.
Like most things, it's probably a bit of both. TVD may have been slightly overrated but Mario also is not giving him a friendly system for him to run to maximize his potential and our offense.
