Stephen Zimmerman is Scout.com's new No. 1 prospect in the 2015 class.
Zimmerman jumped from No. 5 overall to the top spot after an impressive spring circuit, where he performed well with the Dream Vision travel team and at multiple spring camps.
Offensively, Zimmerman is impressive. He has great hands and touch, can score with a variety of moves on the block, but is also skilled enough to step out and hit jump shots or attack from the elbow.
On the opposite end of the floor Zimmerman, a standout at Las Vegas (Nev.) Bishop Gorman, must be accounted for. He's active, plays good help side defense and is one of the best shot blockers in the class.
Malik Newman, a 6-foot-3 guard out of Jackson (Miss.) Callaway, who pushed Zimmerman for the top spot, checks in at No. 2 overall.
Perhaps the most accomplished scorer in the 2015 class, Newman ramped up his game this spring. His scoring arsenal is impressive, as he has range on his shot to go with a developed mid-range game.
Newman led the USA U16 team in scoring with 16.2 points a game in the 2013 FIBA Americas U16 Championship. He also led the EYBL in scoring with 24.7 points through 16 league games.
Oakland (Calif.) Bishop O'Dowd standout Ivan Rabb is now the No. 3 prospect in the 2015 class.
At 6-foot-9, Rabb is an impressive run and jump athlete. He impacts the game with his ability to block shots, rebound and score close to the rim. Through 19 games in the EYBL, Rabb scored 12.9 points and grabbed 11.2 boards.
Labissiere is a 6-foot-11 skilled big man. He moves up and down the floor with ease. He's a very good athlete and impacts the game with his ability to score. He's skilled on the block, but also has an effective jump shot.
Diallo, who took home the NBPA Camp MVP, has had a very strong spring. The 6-foot-9 big man is a hard playing big man. He rebounds extremely well, contests shots and can score on the block. Through 18 EYBL games, Diallo averaged 12.9 points and 9.6 rebounds.
