Lea announced the changes Friday.
Lynch spent last season as quarterbacks coach in Lea’s first year as head coach. Lynch helped the offense deal with an injury to starter Ken Seals and turn in a game against then-No. 10 Mississippi where the Commodores had some of their best offensive production in years.
He was offensive coordinator at Colorado State in 2020 and spent 11 seasons at his alma mater Ball State. He first coached wide receivers, then tight ends before being promoted to offensive coordinator in 2014.
Bailey worked with Lynch at Ball State where he spent six seasons working with Lynch between 2015 and 2019. Bailey just had a one-year stint at Colorado State.
