It was Williams's fourth trip to see Rabb during his junior year.
"Hubert and Coach Williams met with Tami Rabb (Ivan's mother) first because I was still in school," said Bishop O'Dowd head coach Lou Richie. "They asked how each was doing and talked about the end of the season."
Before watching practice, Williams, Richie, Rabb and his mother discussed an unofficial visit to Chapel Hill.
"She talked about the spring and summer for Ivan and trying to get back there to do an unofficial visit," Richie said. ""I think we're looking at (visiting) in the next two months. Ivan would look at a couple of other schools as well while we were there."
The Dragons were busy preparing for the California Open Division championship game. They lost two days after Williams's visit, 71-61, to Mater Dei-Santa Ana. Rabb had 10 points, 16 rebounds and three blocks.
"They (UNC) say that Ivan shoots outside and that he's intelligent," Richie explained. "They say he's hard working, they like his length and his ability to use both hands around the rim."
Last year, Rabb was a gold medalist on the USA Basketball Men's 16U National team, starting three games and averaging 12 points and 9.8 rebounds per game. He could play on the 17U National team this summer. The team will be selected in late July.
In the meantime, Rabb will again play with the Oakland Soldiers 17U team on the EYBL circuit. The UNC staff plans to watch him extensively. What they'll see, according to Richie, is a player who can dominate defensively.
"His ability to block shots and rebound is unmatched," he said. "He's up there (with the best players I've seen), but we'll see. It doesn't matter how good you are now, it matters how good you are when you stop being an amateur. He has a ton of upside and a lot of work to do. Hopefully he'll continue to grow and get better."
The location of the college Rabb chooses to get better at isn't of much consequence in terms of distance from home. Besides UNC, he has offers from Arizona, Louisville, Kansas, UCLA and Ohio State.
"Ivan has traveled a lot and we've made mention that no school… he's interested in the schools that are interested in him," said Richie. "It's never been brought up during our discussion that a certain school is too far away."
Another factor that likely won't impact Rabb's decision? Depth charts.
"I would assume who is going to be there and play with him will be factor more than a depth chart," Richie said. "I don't think he's concerned with where he is at on the depth chart. He would like to play with players with similar goals, work ethic and values."
