Then after seven games, Ronald Curry returned to the court from the football field, pushing Boone into the role of backup.
And lately, Boone has been excelling in that role.
"When I go in for Ronald, I expect out of myself to keep things at the same level if we were playing well," Boone said. "And if we're a little stagnant, to elevate things."
So when Curry fouled out of Saturday's win against Georgia Tech with 5:59 remaining, UNC coach Matt Doherty calmly sent Boone in to face the trapping Yellow Jacket defense.
And Boone produced. He reached career-highs with 10 points and five rebounds, handed out two assists and hit a crucial jumper as the shot clock expired.
"He did a great job," UNC forward Jason Capel said. "He kept his composure, played smart, knocked in some shots and he's a great defender. There really wasn't a letdown when he got in the game."
The same was true in UNC's victory against Duke last Thursday. Boone played 15 solid minutes while Curry struggled through foul trouble and a bruised thigh. Boone didn't score, but he didn't throw the game away either. He handed out three assists and had just two turnovers against the Duke pressure.
"It opened a lot of people's eyes where we have more than one point guard, where the team doesn't change, where we can get the job done if I'm not in the game," Curry said.
