"I've taken two visits – Oklahoma and UCLA – and still got to go to Arizona and I was supposed to go to Florida this past weekend, but I changed it," McCallum said. "I'm going to Arizona the weekend of Halloween and then Florida the weekend after that."
"After those visits I think I might know, but I still want to watch these teams play before I make my decision," he added.
McCallum, a standout at Beverly Hills (Mich.) Detroit Country Day, began the visit process by heading to Norman (Okla.), a place he lived for a few years, to see what Jeff Capel's Sooners had to offer.
"It was a good visit," McCallum told Scout.com. "Coach Capel and their whole staff were good. It was good to get back and see old friends. It was a good overall visit."
Just after his trip to Oklahoma, McCallum, a 6-foot-1, 170-pound floor general, traveled west to see Ben Howland's program in person. He came away with a good view of UCLA's set up and got to know their current players.
"It was real good," he said. "I like their coach staff a lot and all of their players. I got real cool with their players. It was good being out in L.A., the weather was real nice coming from Detroit. It was nice to get out there."
"You just get that feeling that it's a basketball school," he said of UCLA. "The students, the fans just really love basketball and you can just kind of tell being in the gym and seeing the history that's there."
Next up on this list is Arizona. McCallum will head to Tucson (Ariz.) during the last weekend of October. He's already been there once and is excited about seeing the Wildcats scrimmage.
"I'm looking forward to it," McCallum said. "I went out there last year at one point for an unofficial and now I'm going to do my official. They are going to have a scrimmage one day and their fans will be there. It should be good. I'm looking forward to seeing it all in person."
Originally McCallum was supposed to visit Florida this past weekend; instead he'll head to Gainesville (Fla.) the first weekend of November.
"They've recruited me pretty tough," he said of the Gators. "Every school is kind of going with what I'm feeling and what I'm telling them and they aren't pushing me or anything. They've been recruiting me really hard all year."
To go with Oklahoma, UCLA, Arizona and Florida, McCallum said that Detroit is still a possibility, as his father is the head coach.
"They are still in there. My dad has coached me their whole life, so they are on there in case I want to play for him."
McCallum, the No. 7 floor general in the 2010 class, also stated that he doesn't have a leader at this point.
"Everyone is pretty much the same," he said. "That's the way I wanted to go in and go look at all of the schools and just kind of take it from there."
As far as a commitment timetable, McCallum still hasn't made up his mind. There's a chance he'll sign early, but because he wants to watch these teams during the season, he may hold off.
"I think when the time is right the time is right," McCallum said. I think my plan is to take these visits and if I really feel like there's one school that I have to go to I might [sign early], but I do really want to watch these teams play and not just in a practice, but during a real game."
