The 6-foot, 170-pound Luke made his official visit to Notre Dame to take in the Michigan game, and the weekend made an impression not only on Luke, but another important person involved in the process.
"I think it was big for him to take his mom and let her see what that school is all about," said Belles, who played at Notre Dame. "He got to see it this summer on an unofficial visit, so I think he knew about that, but he saw the game day atmosphere, which is quite a difference out there.
"The crowd was definitely as loud as it's been there for quite some time. To actually beat Michigan is a good thing. It hasn't happened in a while."
According to Belles, Luke is also heavily considering Oklahoma and Texas, while Arizona State and Arizona continue to recruit him hard as well. USC was in Luke's top four last month, but Belles did not talk about the Trojans when discussing his player's possible destination.
"I think the biggest selling (point) is to get the people out there on game day and I think Cole was thoroughly impressed with that," Belles said. "I think if education plays a big part in his future, then I think that would be a good landing place for him."
Another key aspect of the trip was Luke's mom being able to meet coach Brian Kelly and absorb the atmosphere on campus outside of game day.
"The biggest thing was to get his mom out there to see it," Belle said. "They want to know their son is going to be in good hands, and not have to worry about him every day."
Luke is set to visit Texas on Oct. 6, and he will be at Oklahoma when the Irish visit Oct. 27.
"Arizona State is not giving up, which is awesome, but Texas and Oklahoma are his only other two visits that I know about," Belles said. "If truly education is an important thing, and I know Cole has talked to me about it, then there is only one other school that can compete with Notre Dame right now, and that would be Stanford. And they're in it, but as far as I know, they're not hot on his trail."
