"He asked what my roster looked like and if we had anybody at his level," said Kowalewski, the coach at Oak Ridge Military Academy.
Kowalewski served as an assistant for McCaffery at North Carolina-Greensboro. Their families have been close for years. The ORMA coach recommended 2011 prospect Jacob Lawson.
McCaffery flew to Oak Ridge during the last contact period in April.
"He was here for the day and got a chance to see (Lawson) work out," Kowalewski said. "(McCaffery) wants to come back in July and see him in a live game setting. We didn't run any 5-on-5 when he was here."
McCaffery hasn't extended a scholarship offer to the 6-foot-8, 225-pound Lawson, Kowalewski said. The forward boasts rides from about 30 Division I schools, which include most of the schools from the Southern, Colonial and Atlantic 10 Conferences. He's received offers from BCS schools that include Seton Hall, Wake Forest, Miami and N.C. State, among others.
"It's really all over the place right now," Kowalewski said of Lawson's recruitment. "In the Big Ten, Iowa and Purdue have shown the most interest. He's intrigued by those two.
Kowalewski said Lawson plans on trimming down his list of potential schools in August and making unofficial visits that month.
"We'd like to wrap it up in the fall as early as we can," the coach said.
Lawson likely will see interest in him increase this AAU season, Kowalewski said.
"He's a tremendous athlete," the coach said. "He gets up and down the floor and runs it like a gazelle. He finishes well around the basket and he's quick off of his feet."
Lawson blocked 206 shots as a junior, which averaged out to about five per game.
"He's the best shot blocker I've ever seen at the high school level," Kowalewski said. "He does it without fouling and with both hands. He'll come from the weak side or catch them on the break.
"With his quickness and long arms, he also gets a lot of steals."
Lawson's offensive game is most advanced in the post. He's working on developing his outside shot, shooting off the dribble and taking the ball to the basket, Kowalewski said.
"He hit 25 threes for us this year and I wouldn't be surprised to see him get 50-60 next season," the coach said. "We're going to play him at the three this season so we prepare him for the next level. I think that's where he'll play in college."
Kowalewski described Lawson as one of the most easy-going teenagers he's ever been around. He's posted a 3.1 GPA. He took the SAT in May and will take the ACT in June.
"He's a good kid from a good family," Kowalewski said. "I have no doubt that he'll be a qualifier."
Kowalewski said the president of ORMA called their school the softest of its kind in the country. Other than wearing uniforms and coming to attention to start the day, it's more geared toward values than military training.
"They teach discipline and respect and being accountable," the coach said. "It's not a boot camp."
Lawson's mind is open as it pertains to recruiting, Kowalewski said.
"He returns every phone call," the coach said.
