my frustration with the decision to make him an OC.

If you're confident you can bring in an experienced staff to support a new OC that came from a high school then go ahead and take a chance on the former Heisman/NFL journeyman.

BUT if your supporting staff isn't going to be a strong one then you cannot afford to let someone learn on the job at this level.

player injuries are not a part of the equation. they happen every year and some years they are devastating, but injuries didn't account losses to teams with inferior talent across the board.
