Go after with some money Kirk Ciarrocca OC/QBs from the University of Minnesota. He has over 25 years of coaching.
Steal a Clemson OC or staff like Cam Aiken
I would say UCF OC but that is Jeff Lebby who I can't believe has a job in college football. But dang UCF offense is really good. Seems he has the Briles touch or is it the head coach that is the real reason their offense is great?
Zak Hill, OC and QB coach for Boise State - I love Boise State coaching tree. They know football.
Which brings me to Kellen Moore who might be looking...
Will Hall - OC and TE coach for Tulane
Jake Moreland - OC/Offensive Line for Western Michigan
Kevin Johns - OC/QBs for University of Memphis
Chad Morris - incredible Texas recruiter. Really good OC. Has game calling experience and head coach experience. However, I'm guessing he will be the next UTSA HC unless TCU gives him and his staff some money.
Kalen Deboer Indiana OC...Very talented
Grant Chesnut - Offensive Coordinator/Offensive Line Coach Kennesaw State
Brad Glen- Offensive Coordinator/Quarterbacks Georgia State - I like this guy... his QBs have been awesome. His starting quarterback has averaged over 2,400 yards passing and more than 600 yards rushing almost every year.
Rob Sale - Lousiana Rajin Cajuns OC/OL coach.
Mike Bobo - HC of CSU. Probably will be out but was a heck of an OC with lots of experience.
Graham Harrell- I don't like him. Same old same old with Texas Tech offense that everyone knows how to defend in the Big 12 and at SMU.
Derek Dooley - offensive coordinator and quarterbacks coach - tremendous energy, knowledge and experience. Could be a great person to either take the OC or to even be a co-OC option with Cumbie. Another guy to help grow up Cumbie as an offensive coordinator. I think Derek would be perfect. NFL experience, University of Tennessee, and Missouri. Has football in his blood coaching family. Has worked with Saban and knows how to compete against tough teams in the NFL and SEC. He knows Dallas. I think he could be the perfect fit.
The search doesnt have to lock you with College coaches there are some great coaches in the NFL or high school too TCU should be looking at.
I expect nothing to happen till after early signing period (unless the new coach can flip or bring in some talent to sign early to TCU. But I expect it's too quick and they will wait).
