The 6-foot-4 Cassell has become a top target of the Cardinals in recent weeks since JaQuan Lyle backed out of his commitment to U of L.
Cassell is from Baltimore, Md., and currently plays at Mariana, Fla., Chipola College for Patrick Blake, a former manager at U of L under Rick Pitino. Cassell has already visited Missouri and Marquette and will visit Connecticut this weekend and is expected to make his decision next month.
"He's a big-time shooter who can play both the one and the two (guard positions)," Blake said. "He's had a lot of interest.
"Louisville saw him this summer and they liked him but at that time they didn't have a spot open."
Cassell originally committed to Maryland but was ruled ineligible last September after spending a year at Notre Dame Prep School in Fitchburg, Mass. Several players from Notre Dame Prep had NCAA issues, but Cassell eventually ended up at Chipola.
Cassell will have three years of eligibility remaining at a Division I college.
His father, Sam Cassell Sr., was a standout played at Florida State and a first round NBA Draft pick in 1993. He spent 15 years in the NBA, was an All-Star in 2004 and scored more than 15,000 career points.
Cassell Sr., is now an assistant coach with the Washington Wizards after winning three NBA titles as a player.
