Littrell comes to Chapel Hill from Indiana where he guided one of the most prolific offenses in the country. Indiana finished ninth in the country in total offense in 2013, averaging 508.5 yards per game. The Hoosiers were 17th in passing offense (306.7 avg.) and 30th in rushing offense (201.8). Indiana was one of only three teams to average more than 300 yards passing and 200 yards rushing.
"Seth has been a successful offensive coach and recruiter everywhere he's been," said Fedora. "He played on a national championship team at Oklahoma and has worked with some of the best college coaches in the country. When I was at Oklahoma State and he was at Texas Tech, we coached and recruited against each other.
"I believe he'll be a great fit for our program and for this University. He will bring some new ideas to our offensive system and I'm excited to have him in Chapel Hill."
"I'm excited to be here and look forward to working for a great institution," said Littrell. "This is a great coaching staff and I can't wait to meet our players and get to work."
