"I'm very excited," said the Dudley High (N.C.) senior forward. "I've waited for this all my life. This means the world to me."
Graves will sign his letter of intent at a 12:30 p.m. ET ceremony in which his friends and family will be in attendance.
"I'm just ready to sign the papers and make it official," he said.
Then Graves can concentrate on getting healthy.
Graves said he injured his left ankle on the next to last day of Nike Camp in early July and then played with the injury for the latter part of the month at tournaments in Atlanta, Las Vegas and Los Angeles.
"I wanted to keep playing, so I taped it up," Graves said. "But it didn't get any better."
Graves went to the doctor when he returned home at the end of the summer he discovered it was scar tissue and inflammation, which required minor surgery about a month ago.
"I really haven't done anything since the surgery," Graves said. "I just started riding a bike the middle of last week and practiced for the first time today (Tuesday). It was good at first, but then I started jumping and that wasn't working real well."
Graves has still set a target return for Nov. 22 – which is the date of the season-opener.
His biggest challenge this season?
"Dominating the game," Graves said. "Having a killer instinct."
While Graves is excited about signing the paperwork and also thrilled with the quality of the Tar Heels six-man class, he's only seen one of the other five signee play: Brandan Wright.
"This is what you live for," he said. "To come in with this type of talent. Brandan is the only one I've seen play – I played with him in 3-on-3 at Nike Camp. He's an outstanding player who you have to double team to stop. You can't stop him with one person. He dominates games. He's an outside presence and also a nice mid-range game. He's just a great player overall."
