He's 16-16 in FBS, all his other experience was FCS. He bailed on Delta State after one season going 3-7, had 2 losing seasons at Costal before showing out this season.
Also even at the FCS level he's already been in NCAA trouble:
In 2018, the NCAA released a detailed report concerning numerous NCAA violations that occurred during Chadwell’s tenure as the CSU head football coach. The violations ranged from using multiple ineligible players to players using scholarship funds to purchase electronics and jewelry from the campus book store. Ultimately, the NCAA sanctions vacated 18 wins from the 2014 and 2015 seasons and the 2015 Big South Championship. Also vacated were three wins over crosstown rival The Citadel, games during which CSU used ineligible players.
