Early in his junior season, Williams had tests and learned that his knee pain was due to inferior bipartite patella, a rare congenital condition requiring surgery.

[3] Following his redshirt junior season, Williams graduated from UCF and entertained transferring for his remaining year of collegiate eligibility.

He originally chose to transfer to Wake Forest, but ultimately changed his mind and returned to UCF for his final year to play for new Knights coach Johnny Dawkins.

[4][5] In his fifth year, Williams upped his scoring average from 8.1 to 15.1 points per game, helping lead the Knights to the semifinals of the 2017 National Invitation Tournament.

[7][8] On October 15, his contract was converted to a two-way deal, meaning he'd be able to split playing time between the Heat and their NBA G League affiliate, the Sioux Falls Skyforce.

[10] He appeared in a total of 3 games, tallying 5 points and a rebound in 11 minutes of action before he was waived on New Year's Eve in order for the team to sign Derrick Jones Jr.[11] Williams was later reacquired by the Sioux Falls Skyforce.
