"I've gotten up to 225 now," Zeller said. "Just from lifting a lot this summer."
College coaches followed the slender big man this summer while he toured with the Spiece Top Dogs as well as attending the Nike camp. Months later, Zeller has over 30 scholarship offers from Division I programs.
Among the notable schools on his list -- Iowa, Indiana, Purdue, Marquette, NC State, Notre Dame, Xavier, Illinois, Louisville and Missouri. And probably by the time this article gets published -- he'll have even more.
"The offers are coming in pretty quickly," he added.
But the big man insists that while he's still open to more attention, he hopes to make his list smaller by the end of the season.
"I'm hoping to figure out the top five by the end of the basketball season and then take my official visits," he noted. "I don't have any leaders as of right now."
Sources have confirmed that the staff at North Carolina has some interest in Zeller after this summer, and the big fella was able to confirm that the feelings were indeed mutual.
"I had been looking at Kansas awhile ago, just because of Roy (Williams), I am still interested in his program now at North Carolina," he said. "I took a visit out to Kansas when he was there and I spent some time with Coach (Steve) Robinson when I was out there.
"They came to my school about four weeks ago for my open gym. Coach (Joe) Holladay was there. (UNC) hasn't really said anything to me yet, but I think I'd like to get out there after my season to take an official visit."
