The players who won gold -- the majority of whom are set to begin their freshman seasons -- will benefit from the competition and the spirited workouts and playing for Florida's Billy Donovan, Gonzaga's Mark Few and VCU's Shaka Smart.
The U.S. didn't lose a game in the FIBA Americas U-18 Championships and won by an average of 39 points, including beating host Brazil twice.
High schooler Julius Randle, who still has another year at Prestonwood Christian Academy in McKinney, Texas, led the Americans in scoring at 14.2 points and 6.6 rebounds a game.
Tennessee sophomore-to-be Jarnell Stokes was second at 14 points and 5.6 rebounds a game.
I asked Donovan for five players he is convinced will have a major impact on their respective teams during their first college seasons.
He didn't hesitate on the first name (tourney averages in parentheses). Marcus Smart, 6-foot-3, SG, Oklahoma State (7.4 ppg, 3.4 rpg): "I have not been around a player in a long, long time that is as good a competitor. He can shoot the ball better (1-of-10 on 3-pointers), but he's unselfish and an unbelievable leader. He was absolutely terrific. He's a terrific player. He's special. He has the internal qualities to me.''
Jerami Grant, 6-7, SF, Syracuse (5.6 ppg, 5.0 rpg): "He didn't shoot very well (7-of-25), but he'll end up being a Kris Joseph or Wesley Johnson for Syracuse in time. He's rangy, long and can play two different positions. His upside may be greater than anyone else on the team. He's so long and athletic. Once he knocks down shots he'll be really special.''
Sam Dekker, 6-7, SF, Wisconsin (5 ppg, 2.5 rpg): "He was hurt, ended up spraining his ankle, and then someone stepped on his toe and that had to be drained. He was never quite healthy. But he's a warrior. He loves to play. He wants to win. I think he's a really good player. He takes some crazy shots. I just wish I could have coached him. He's going to be terrific.''
Shaq Goodwin, 6-8, PF, Memphis (12.4 ppg, 4.8 rpg): "He's got a chance. He scored 30 points in our first game. He's got a great feel for how to play. He's got a big body. He needs to be a bit more serious. But he played pretty well while he was there. He did a nice job for us.''
James Robinson, 6-3, PG, Pittsburgh (4.4 ppg, 2.6 rpg): "We weren't sure we were going to keep him. We cut the team from 25 to 14 and then kept guys around to 12. He was originally on the outside looking in. But once we started practicing we saw that he's a winner and a great role guy. He's a typical Pitt player. Jamie [Dixon] will love coaching him. I'm not sure of his impact on the team, but people will say, 'Where did this guy come from?' The kid is a winner. I liked coaching him. He was the same guy every day.''
He said Purvis is an exceptional talent but can get too wrapped up in scoring at times. He's an exceptional athlete, according to Donovan, very physical and a really good player, but needs to check the expectations a bit. Donovan said Sulaimon (10 ppg, 3.4 rpg) needs to avoid feeling too much of the natural pressure that comes with being a highly touted Duke recruit. He said he loved Sulaimon's work ethic and enjoyed coaching him but he just needs to chill a bit.
