I don't think this swing and miss says much about GT.
Texas Tech just finished 6-6, but fired their coach and hired a new one. That staff should have a few years to build things. As others said Kittley is from there, family lives there, graduated from there, coached there for five years and his dad coaches there. WKU is his first experience outside Texas. He knows Texas, Texas recruiting and TT historically has run a similar offense. Success there has springboarded other OCs to Big12 HC jobs.
Georgia Tech just finished 3-9 (again), our coach is on a very hot seat, Kittley doesn't know GA recruiting, and we're still purportedly transitioning from a flexbone offense. If the coaches are not successful next year (and they're not set up to be). They're probably getting fired. He's an up-and-comer, a bad move could derail his career.
Kittley would be crazy to come here when his alma mater has a better situation to offer. Even if GT offered more money.
