This time around Zeller took in a football game, played pickup with the team and former Heels now in the NBA and got the full tour of the Chapel Hill campus. Now that the 6-foot-11, 220-pound power forward has researched the Heels, he's trying to figure out if they are the best fit for him.
"North Carolina is a great school and they have a legendary coach," Zeller said. "They like to run and that's what I do best, but they have a lot of talent so it'll be interesting."
The weekend after visiting UNC, Zeller traveled to Bloomington to see what Indiana had to offer. Zeller said he has formed a tight bond with the Hoosiers staff, despite the NCAA sanctions that were in place for the head coach.
"With Coach Sampson's sanctions I talked to his assistant coaches a lot and I talked to Coach Sampson after his sanctions were over so I got to know their whole coaching staff very well."
After taking two weeks off, Zeller resurfaced at Notre Dame for his third official visit. With the Fighting Irish, Zeller would have the chance to play alongside his brother for a year, but that doesn't seem to be a major factor in his decision making.
"It would be fun, but it's not essential because he'd only be there one year and I'm going to be at this school for four years," he said. "We also don't play the same, so it's a good fit for him, but I've got to look at it and see if it's a good fit for me."
Zeller, who is ranked No. 16 in Scout.com's latest rankings, ended his visit spree this past weekend, as he took a trip to Purdue. Zeller had already developed a strong relationship with head coach Matt Painter, so he used his time to get to know the players.
"For the most part, I just hung out with the players," Zeller said. "All of the other times I've been up there the players have been gone or I couldn't play with them. This time I got to hang out with and play with them, so it was a good visit."
With the four visits complete, Zeller is closing in on making his college decision. Prior to taking his final visit, one school seemed to take the lead, but that has now changed.
"Not anymore," he said, when asked if he had a leader. "Probably before the Purdue visit [I did], but now it's all pretty even."
With the November signing period just around the corner, Zeller hopes to announce his college decision at a press conference in two weeks.
"I'm going to pick a school now and hopefully sign in November between the 14th and 21st. I'm hoping I can make my decision before that, maybe around the 5th so I can get it done before practice starts."
Despite the big decision coming up, Zeller said he's just happy to get a chance to hang out and be a regular high school student for a few weeks.
"It's kind of a nice that I don't have to put up with [visits] anymore," Zeller said. "I'm going to have some free weekends to just hang out with my friends."
