And the Cardinals will be the first school to host Lee on an official visit.
The 6-foot-9, 225-pound Lee will visit U of L the weekend of Sept. 7 before heading to Kentucky on Oct. 12 and Indiana on Oct. 28. He will visit Duke and Kansas this winter and is also considering UCLA and California.
"It's about trying to figure out the best situation for Marcus," said Lee's brother, Brian, who is handling a lot of the recruiting details. "It's tough to say what schools are really in there because everybody really started recruiting him in April.
"The visits are important. With Marcus recruitment, it came as a rush and all of a sudden we had 40 schools in front of us. So, now we're start building these relationships and just seeing where it all goes."
Lee is the No. 37 player in the Class of 2013 and the No. 2-ranked center.
Brian Lee said his brother is on the phone once a week with each school and noted U of L assistant coach Wyking Jones, "has been great to deal with."
Jones saw Lee at the first Nike Elite Youth Basketball League session in Minneapolis back in April and the Cardinals offers just after the event.
Brian Lee said the Cardinals have been after his brother every since. The staff watched him in every event they could during the spring and summer with U of L coach Rick Pitino coming to several games in July.
"The interest with Louisville got stronger as the summer went on," Brian Lee said. "They're doing a great job staying in contact with Marcus and the system seems like it's a great opportunity. They play hard and they play defense."
Brian Lee said Pitino was a "big draw" for the family and noted Marcus Lee "really likes to play defense," and was impressed with the Cardinals.
"At first we just knew they played defense and Rick Pitino's name speaks for himself," Brian Lee said. "We're building a lot of it new relationships and talking to Wyking a lot. It's nice to hear the plans they have for Marcus."
Lee is from California but his brother said he spends most of the summer in Texas and noted that location isn't going to be a factor.
"It's more the program for him," Brian Lee said. "The location doesn't matter so much. He's not too nervous to leave home. Plus, he's accepted the fact that if he wants to continue to play basketball it could end up being anywhere."
