College career Oklahoma State As the nation's No. 1 recruit in the Class of 2014, Marsteller signed with Oklahoma State University. He redshirted his first season in 2014–15, compiling a 14–4 overall record and picking up two wins over ranked opponents.Chance Marsteller - 2014-15 - Cowboy Wrestling. okstate.com. Retrieved February 6, 2025. He made his Oklahoma State debut on November 14, 2015, before 42,287 fans at Iowa's Kinnick Stadium, winning his dual meet match with a 14–11 score. He finished his redshirt freshman 2015–16 season with a 6–5 record. Marsteller later spoke of how his weight cut down to the 157-pound weight class that year, a weight he hadn't wrestled since his freshman year of high school, feeling disconnected mentally, and wanting to be closer to home, led to his decision to transfer after the season.

Lock Haven He transferred to Lock Haven University, a school three hours from his hometown in Pennsylvania, in May 2016. However, Marsteller had been in a steady decline with alcohol and drug addiction, which started to intensify during his college years. On August 25, 2016, Marsteller was charged with aggravated assault, simple assault, recklessly endangering another person, disorderly conduct, and open lewdness after police arrested him for harassing the residents of an apartment complex in Lock Haven. He was subsequently kicked off the wrestling team and out of school and sentenced to a seven-year probation. Using that incident as a motivational tool to redeem himself and turn things around, Marsteller had a successful stint at rehab, re-enrolled at Lock Haven in the 2017 spring semester, finished that semester with a 4.0 GPA, and was embraced with support being back home.Pyles, Christian (June 29, 2017).

While turning things around and finding success on and off the mat, Marsteller later came out with how he had relapsed and continued to struggle with drug addiction throughout college. This would hinder him from reaching his potential, as he knew he wasn't competing near his ceiling of capability. Opioids, fentanyl, and heroin were different drugs he would use, and though he continued to manage training, practicing, and going about day-to-day life, his drug addiction was worsening and growing stronger.Smirnova, Lena.

Retrieved February 8, 2025.

Freestyle career Marsteller would continue his wrestling career on the senior level circuit, following his collegiate career in 2019.

In 2020, after driving under the influence and wrecking his car and his wife's car in one night, Marsteller entered rehab again. After almost losing everything, he sobered up for good in July 2020, while also rebuilding relationships with his family.

Around the start of 2022, Marsteller began visiting the New York City Regional Training Center in Hoboken, New Jersey, and ultimately moving there for more individual coaching and a strong group of wrestling partners.Zaccardi, Nick.
