The 6-foot-8 power forward averaged just 0.9 points and 1.1 rebounds last season, before seeing 11 minutes in three games this season.
Agau was an ESPN 100 prospect coming out of Omaha Central (Neb.), but never carved out a role with Louisville. Freshman big men Chinanu Onuaku, Anas Mahmoud and Jaylen Johnson all saw more minutes during the non-conference portion of the season.
"This has been a great opportunity for me," Agau said when he left Louisville in mid-December. "I want to thank Coach Pitino and the entire staff. I learned a lot in the two years I have been here and built a great connection with everyone. Everyone in this program is part of my family and it is sad to leave, but this is the best decision for me. I'm always going to be a part of the Louisville family."
Agau is expected to be eligible to play after the first semester next season, and will have two-plus seasons to play. The Hoyas are also bringing in four-star post players Jessie Govan and Marcus Derrickson next season.
