"They asked me if I was interested in them," Griggs told InsideTennessee, "and I said yes."
That had to be encouraging for the Tennessee staff because Griggs was one of the more impressive players at the camp. The 6-foot-7, 205-pounder grabbed rebounds, blocked shots and showcased some offensive versatility.
Asked what he enjoyed most about the Vol camp, Griggs replied: "I like that I played with other athletes with ability like mine."
Few of the competitors played as well as he did, however. He came away generally pleased with his performance.
"I'd rate it as a 9," he said. "There are some things I've still got to improve on."
Griggs established himself as a rising star during his sophomore season at Newnan (Ga.) High School last winter. He says his best outing was a triple-double against East Coweta High.
"I had 24 points, 12 rebounds, 10 blocks and 4 assists," he recalled. "I've had several triple-doubles but that was a rival game, so that's the one I'll always remember."
His best game representing the West Georgia Elite traveling team this summer, he said, came in a tournament at Suwanee, Ga., when he produced "21 points, 5 assists, 12 rebounds and 8 or 9 blocks."
Griggs says his favorite NBA player is Kobe Bryant, adding: "He can shoot and he's an all-around player."
Griggs is working to become an all-around player, too.
"I'm an inside/out person," he said. "I like to play inside to outside. I like to get the rebound and get the ball to the outlet person."
Noting that he is looking for a university that combines "good athletics and academics," Griggs said he is getting a lot of interest from four schools — Virginia Tech, Tennessee, Georgia and North Carolina.
With two years of high school ball to mature physically and refine his skills, Griggs has a chance to be an elite prospect by the time he's ready to enter college.
"I still have some things I've got to work on," he admitted. "I need to improve on getting stronger, improve my moves in the paint and get a better basketball IQ."
