Hue Jackson, the current OC for the Cincinnati Bengals.
He's coached a long time at both the NFL and college levels.
He recruited and developed Carson Palmer during his QB/OC days at USC.
The first 2 head coaches who gave him play-calling duties were Steve Spurrier and Bobby Petrino, two of the best offensive minds in recent history. The interesting part there is that both coaches never let anyone else call plays for them aside from Jackson. That's the type of respect he has.
His next stop was in Oakland, and the Raiders went from the absolute bottom of the league in total offense to 5th overall. That was the highest one-year yardage rank jump in the history of the league.
He explained his style and approach to the Oakland Daily Journal at the time:
"We're gonna be a fiery, get-after-you, come-get-you football team. That's what we're going to do."
He served one season as head coach of the Raiders (8-8) before they made wholesale changes (similar to Chud in Cleveland).
He's a tremendous offensive mind. His swagger reputation would seemingly make him a great fit for the South Florida football culture. He's worked at both levels. He has NFL head coaching experience. There are a lot of reasons why I'd love to see UM make a run at him.
