PORTLAND, Ore. – With LSU-bound Ben Simmons leading the way on the court, the 125 credentialed NBA personnel had good reason to be excited about future prospects while watching the 18th annual Hoop Summit game and practices last week.
The NBA draft has been loaded with one-and-done college freshmen in recent years and this year's draft will be no different with the likes of top-pick contenders Karl-Anthony Towns and Jahlil Okafor, who are both Hoop Summit alumni. The U.S. Junior National team lost 103-101 on Saturday to a World Team that included players under 19 years old. The 2016 NBA draft could be led by such Hoop Summit participants as Simmons, Kentucky-bound center Skal Labissiere and undecided forward Jaylen Brown. If Canadian guard Jamal Murray, who scored a game-high 30 points, and Australian forward-center Thon Maker reclassify to go to college next school year, next year's draft class would get even stronger.
"There were two to three NBA starters, then there is a drop-off that will be determined by development," an NBA scout told Yahoo Sports. "A lot of the wings were good players, but don't have the prototypical size now. There are a few sleepers, too."
The following is Yahoo Sports' top 10 high school players the NBA has its eyes on in the Class of 2015:
1. Ben Simmons, Australia, 6-9, forward, LSU
Scout's comment: "He can play multiple positions. He can guard multiple positions. Super passer. His jump shot is a little shaky, but it will get better. He is going to be a special player."
2. Skal Labissiere, Haiti, 7-0, 216 pounds, forward-center, Kentucky
Scout's comment: "He has a major upside. He is already long, athletic, coordinated and moves very well. He can also step out and shoot it and block shots."
3. Jaylen Brown, Alpharetta, Ga., 6-8, 217 pounds, forward, undecided
Scout's comment: "He already has great size for his position. He is a lock-down defender and very athletic. A very good shooter who can get to the cup."
4. Cheick Diallo, Mali, 6-9, 230 pounds, forward, undecided
Scout's comment: "He's a Kenneth Faried-type. All energy, hustle and motor. However, his big issue is that he does not have a skill set."
5. Ivan Rabb, Oakland, Calif., 6-8, 191 pounds, forward-center, undecided
Scout's comment: "I love everything about his game. Very skilled. But will he be the same player when he plays taller players in college? He needs to add upper body strength."
, Milwaukee, 6-10, 250 pounds, center, Maryland
Scout's comment: "Surprising he wasn't invited to the Hoop Summit. Some say he is a 'me-first' guy, but I disagree. Can really score. Skills like Zach Randolph. Can finish with both hands."
7. Brandon Ingram, Kinston, N.C., 6-9, 190 pounds, forward, undecided
Scout's comment: "Very skilled player who is super long and athletic. He can play multiple positions and has a nice shooting stroke. He needs to get stronger and gain weight."
8. Henry Ellenson, Rice Lake, Wis., 6-10, 231 pounds, Marquette
Scout's comment: "Did not play in the Hoop Summit and a lot of NBA scouts have not seen him yet. Skilled player who has trimmed down and is comparable to Kevin Love."
9. Malik Newman, Jackson, Miss., 6-3, 176 pounds, shooting guard, undecided
Scout's comment: "Has a mid-range game, can shoot 3-pointers and is good scoring off of screens. A legitimate shooting guard."
10. Stephen Zimmerman, Las Vegas, 7-0, 230 pounds, center, undecided
Scout's comment: "Reminds me of a young David Lee. He has size. Shoots left-handed. A heck of an athlete."
