It's the resume of an assistant coach following opportunity and using relationships. When he showed up in San Marcos, I was less than impressed and wondered how this guy was even in coaching. Dude has moved up a level in school or coaching rank at most every stop and did pretty well as a DC his last 2 stops.
2014 - Elko was the DC at Wake Forest, and that's the key to most of his movement. Mind you, he wasn't a position coach here, just an assistant/GA.
2016 - Withers is hired at TXST, and that staff was random af - you could tell he was pulling in guys from anywhere. Santucci is done w/ GA, ready for a full time gig.
2017 - Elko gets the DC job at ND, takes Santucci w/ him as an analyst because he's not ready to be a position coach at that level.
2018 - Elko gets the DC job at aTm, takes Santucci w/ him as an analyst because he's not ready to be a position coach at that level.
2019 - Lyle Hemphill gets the DC job at Wake. Hemphill was the DC at Stonybrook in 2012-13, where Santucci was coaching S and DL under him.
2020 - Elko hires him as LB coach at aTm, gets promoted to Co-DC when Elko goes to Duke
2023 - Elko hires him as DC at Duke, and he actually does a pretty good job - 2ppg and 26 fewer yards per game than 2022
2024 - Pretty sure this is the 1st job he got w/o a relationship, and again, does a pretty good job - 4ppg and 95 fewer yards per game than 2023
