Kenyon (K.J.) Lewis grew up in El Paso, TX and played under coach David Peavy, father of former Georgetown forward Micah Peavy, at Duncanville HS in the Dallas suburbs. A two year reserve at Arizona, he averaged 10.5 points as a sophomore, shooting 42 percent from the field and with 22 double figure games as a sophomore. Lewis had six starts as a sophomore behind starters Caleb Love and Jaden Bradley, who led the Wildcats in scoring.

Lewis succeeded Jayden Epps (2023-25) in the Georgetown backcourt, averaging 14.9 points per game and earning third team All-Big East post season recognition. A formidable option on defense, he led the Hoyas in steals and was third in rebounding, leading the Hoyas in scoring in 14 games in 2025-26.

He posted six games of 20 or more points for the Hoyas, including a season's best 27 versus St. John's and 26 at Providence. A foot injury on February 24 ended his season, whereupon he announced a transfer at season's end.
