Before you ask UConn has had two five stars in Hurley's tenure:
Akok Akok (2019, injuries ruined his promising start)
Stephon Castle (2023)
So Scheyer has had 5, 2, and at least 2 in three recruiting years, with one de-committing, for a total of 9 (10).
For fun, for UConn to match the same number of five stars Scheyer has signed/had commit in three classes (as of September 24, 2023) you have to go back 20 classes:
Hurley has had two, as mentioned.
Ollie had Jalen Adams (2015) and Daniel Hamilton (2014) as five star freshmen.
Calhoun had Andre Drummond (2012), DeAndre Daniels (2011), Kemba Walker (2008), Rudy Gay (2004), Charlie Villanueva (2003)
Technically Scheyer had one more signed with Mgbako but that evens out with Bynum (2005) as neither played for Duke or UConn respectively.
I don't think I missed any.
