You raise an interesting question Alex.
I think we all know that Oregon has never been a "coaching up" school. That doesn't mean that Oregon never had any great players. It just means that either the player has what it takes before getting to Oregon or he/she wont be one. Oregon does not coach players to greatness.
Justin Herbert was a great player surrounded by mostly mediocre players and coaches. Keep in mind that it takes more then one great offensive lineman to help a QB achieve greatness.
In the NFL Justin has the opportunity to become someone special at the Chargers. To try and achieve that the Chargers ownership has brought in a new head coach to bring that to light. We will have to wait to see it that will happen but I have to question if the Chargers ownership itself is capable of producing a championship organization. After all it's had plenty of time to do so in the past, but sank to a No. 6 draft pick in the first round.
The Chargers Ownership has made mistakes in the past like it's move out of the San Diego area into LA. And it's keeping of it's QB, Rivers all these years, one who has always been just one step above mediocracy but never great.
Keep in mind that Justin Herberts winning of the NFL rookie of the year award was done on his own merits not the organizations.
