A member of the U of L staff was at every game the 6-foot-9, 240-pound Alexander played in Sin City. He helped Mac Irvin Fire to a win in The Eight tournament and a semifinal appearance in the Las Vegas Classic.
"It was a really good summer," Alexander said. "I just played my game, just wanted to try and improve and win. I think it went good."
While Alexander did sit out the final three games of the summer because of a thigh injury, his summer "went great," and was successful for him and the team. He had coaches swarming around his games all summer.
Alexander said he's "no where near" making a college decision but did narrow his list earlier in the month to Kansas, Kentucky, Louisville, Michigan State, Illinois, DePaul, Indiana, Memphis, Baylor and Arizona, later adding Florida.
"It's going good since I cut my list," he said. "I added Florida to make it those 10 schools and Florida. I am really open to everybody right now.
"I don't have a favorite and I don't know when I will have a favorite. I just want to make the right decision for me."
Alexander said he knows he wants to take official visits to U of L, Kansas, Memphis and Arizona with the fifth up in the air.
"It's going to be a tough decision," he said. "I'm not sure when I will be ready."
The Cardinals are hopeful the list of visits will remain the same with Alexander perhaps getting to the U of L campus later next month. He has talked a few times to Rick Pitino and is "building a relationship" with the staff.
"Louisville will definitely get a visit," he said. "I'm not sure when yet, but they will get a visit. They have a great staff and I really like how they use their post players in the offense, letting them run the floor."
Alexander played alongside U of L commitment JaQuan Lyle in Vegas and the five-star guard said he was "in his ear a lot."
"They just wanted me to know I could play with them, and it would be fun," Alexander said of the guys trying to recruit him to certain schools.
Alexander is listed as the No. 6 overall player – and No. 3 center – in '14.
