"Every time I step on the court, I feel like I have something to prove," Harrell said. "I just want to get better every time."
And better he has gotten.
"South Carolina is the school that has shown the most interest," the 6-foot-7 North Carolina native said. "They stay trying to keep in contact with me, and they always want to keep up with me."
The North Edgecombe standout admits that this has really benefited South Carolina, and he is humbled by it as it helps motivate him to just keep getting better.
In fact, the Gamecocks even went as far as bringing their whole coaching staff to one of his high school games last season.
"It was real good to have them bring their whole coaching staff," Harrell said. "It was a big part of my basketball career."
To go along with his South Carolina offer, Harrell claimed offers from Virginia Tech, Clemson and Xavier, but he admitted to fielding a ton of calls since the contact period began on June 15.
Though it may be tough to pull him out of ACC country, the Gamecocks still standout thus far.
"They play hard every time," Harrell said of South Carolina at the Bob Gibbons tournament. "They press all game. They are going to get in your face every time they play defense."
Harrell is impressive on the basketball court, but he also had a coming out party in another sport last month as well — track.
"Track is something that I tried and found out that I was good at," he said. "I ended up winning the Regionals (in the discus) and finishing sixth in the state.
"I just wanted to try something new."
As far as getting Harrell down to Columbia, it looks like he'll trip to campus after his AAU season ends at the end of July for the elite camp.
"I'm going to their elite camp," he said. "And I think I'm going to visit the campus then."
Although Harrell is only a rising junior, he still has an idea on when he wants to make his decision.
"I'll look at making a decision at the end of my junior season or at the end of my AAU season," he said.
