An aggressive center,[1] Schull played collegiately for Florida State before forging a successful professional career in Italy where he led the Serie A in scoring for a season.

[5] Despite reportedly being offered a $12,000 contract by the NBA's Seattle SuperSonics in 1968, Schull chose to join Eldorado-sponsored Fortitudo Bologna in the Italian Serie A for $1,000 more, mostly because he wanted to experience life abroad.

[6] Schull quickly gained the fans' admiration with combative displays, for example diving in the stands to reclaim a loose ball on his debut, something unusual at the time.

[7] Schull played a further two seasons for Fortitudo Bologna before retiring from basketball in 1973 after struggling with injuries, returning to the U.S. to be closer to his sick mother and work in his father's building company.

He ended his Fortitudo career having appeared 104 times for a side continuously flirting with relegation, scoring 2,339 points (over 22 per game) and leading the rebounding tables twice in addition to his top-scoring crown.
