Marcus Bartley -- 2014 -- PG -- Peoria Irish

Keita Bates-Diop -- 2014 -- F -- Illinois Wolves
6'8 -- University H.S. -- Bloomington, IL

6'8 --White Station H.S. -- Memphis, TN
The Memphis native is one of the more productive forwards in the country and has a slew of high-majors tracking his every move. The former Baylor commit is a double-double waiting to happen, but he's also improved his three-point stroke this spring and summer.

Trevon Bluiett -- 2014 -- SF -- Team Detroit
6-5 -- Park Tudor H.S. -- Indianapolis, IN
One of the best shooters in the class, Bluiett is also a well-rounded scorer that can put the ball in the hoop in a number of ways. When he gets hot, he can go for 30-plus points in any game.

Joe Burton -- 2014 -- SF -- Houston Defenders
6'6 -- Atascocita H.S. -- Houston, TX
A veteran of the 17U scene since he burst onto the scene with the Franchize All-Stars as a rising freshman, Burton now has the spotlight on him with the Defenders. His perimeter stroke and skillset have improved a lot in the last year and he's also a willing rebounder and defender on the wing.

CJ Carr -- 2014 -- PG -- Quad City Elite
5'7 -- Rock Island H.S. -- Rock Island, IL
After leading Quad City Elite to the NY2LA Sports Next Level Invitational title last weekend, we'll see what Carr and his teammates have in store for a follow-up act. Carr runs an offense, gets to the rim, has great body control and is also a pest on the defensive end.

Shaquille Carr -- 2014 -- PG -- Las Vegas Prospects
6'1 -- Canyon Springs H.S. -- Las Vegas, NV
One of the better uncommitted point guards in the 2014 class, Carr runs a team very well while also displaying a tight handle. He's also very good in transition and can finish in the air thanks to his hang time.

Brekkott Chapman -- 2014 -- F -- Utah Prospects
6'8 -- Roy H.S. -- Roy, UT
The versatile lefty forward can go inside and outside and will drop in hooks or perimeter jumpers if left open. He also defends multiple positions and rebounds well from the wing as well.

Chris Chiozza -- 2014 -- PG -- Team Thad
5-11 -- White Station H.S. -- Memphis, TN
The Florida commit is one of the most exciting players in the country and plays at an incredibly fast pace while also remaining under control. Chiozza has tremendous body control and can finish through contact against bigger players because of his strength.

Dominique Collier -- 2014 -- G -- KC Run GMC
6'2 --Denver East -- Denver, CO
The Colorado commit can play both guard spots and can knock in shots from the perimeter or get to the rack. As a point guard, Collier reads screens very well and can find teammates for easy buckets.

Darrell Davis -- 2014 -- SG -- Michigan Hurricanes
6'4 -- Douglass Academy For Young Men -- Detroit, MI
One of the better prospects from the state of Michigan, Davis is a combo guard that can score and also handle a bit for his team as well.

DJ Davis -- 2014 -- SG -- Net Gain Sports
6-3 -- Bloomington Kennedy H.S. -- Bloomington, MN
Davis shot the ball well in the Next Level Invitational and will be a prospect to watch this week for low-major programs. He played hard on both ends of the floor and also played the passing lanes a few times for steals.

James Demery -- 2014 -- SF -- Team Charlotte
6'6 --Northside Christian H.S. -- Charlotte, NC
Demery gets to the rim as well as many wings in the class and had a great NBPA Top 100 camp last month. Demery can get on a roll as a scorer and be really tough to stop.

Jarvis Garrett -- 2014 -- PG -- TP Elite
5-10 -- Notre Dame Prep -- Milwaukee, WI
After a strong Next Level Invitational, Garrett will look to follow that up at the Summer Jam. Garrett gets others involved, defends the length of the floor and also scores in a variety of ways.

Nate Gehring -- 2014 -- C -- Kingdom Hoops Elite
6-8 -- Waukee H.S. -- Waukee, IA
The lefty big man has been a priority for mid and low-major programs in July and rebounds his area and has some nice post finishes with his left hand.  He can also defend his area and block some shots as well.

Malek Harris -- 2014 -- F -- Illinois Wolves
6-7 -- Sandburg H.S. -- Orland Park, IL
The Marquette commit has one of the highest-running motors in the country and does a tremendous job on the glass while also improving his skillset on the perimeter. You can pencil Harris in for a double-double nearly every time he hits the floor.

Chase Jeter -- 2015 -- C -- Dream Vision
6-8 -- Bishop Gorman H.S. -- Las Vegas, NV
A big with good hands and a nice touch on the interior, Jeter gets off the ground quickly and is productive on the glass alongside teammate Stephen Zimmerman. They form a tremendous tandem inside.

Derrick Jones -- 2015 -- SF -- We R 1
6'5 -- Archbishop Carroll H.S. -- Philadelphia, PA
A wing that attacks the rim as hard as anyone, Jones can make some highlight-reel plays if he gets going towards the basket. Jones also has the ability to score from all three levels and is one of the better prospects in the 2015 class nationally.

Riley LaChance -- 2014 -- PG -- Ray Allen Select
6'2 -- Brookfield Central H.S. -- Brookfield, WI
It's fun to watch LaChance play because he has a high basketball IQ and can make plays as a passer, or a high-level shot maker. LaChance makes some difficult shots and also has an improving runner and floater game.

Scott Lindsey -- 2014 -- SF -- Illinois Old School Woods
6'6 -- Fenwick H.S. -- Hillside, IL
Lindsey shots the ball at a high level and has prototypical size for a wing shooter. He can also hit some pull-ups and go off the bounce, but shooting off of screens is his calling card.

Wyatt Lohaus -- 2014 -- PG -- Iowa Barnstormers
6-2 -- Iowa City West -- North Liberty, IA
The Northern Iowa commit has one of the better mid-range games in the class and plays with a high level of toughness and tenacity. As a point guard, Lohaus is steady with the ball and limits turnovers.

Kevon Looney -- 2014 -- F --Milwaukee Rebels
6'9 -- Hamilton H.S. -- Milwaukee, WI
One of the best rebounders in the country, Looney is great on put backs and also destroys defenders when operating out of the high post. Now that his perimeter jumper has improved, he's nearly unstoppable if he gets rolling.

Jaquan Lyle -- 2014 -- G -- Mac Irvin Fire
6'4 -- Bosse H.S. -- Evansville, IN
One of the top guards in the country, the Louisville commit is a tremendous passer but can also score the ball in a variety of different ways. His work out of the mid-post is among the best for guards in the country.

Caleb Martin -- 2014 -- SF -- Team Loaded
6'6 -- Davie County H.S. -- Mocksville, NC
Along with twin brother Cody, the North Carolina State commits are versatile wings that can shoot or take it off the dribble to get buckets.

Yante Maten -- 2014 -- PF -- Team Detroit
6-8 -- Bloomfield Hills Lasher -- Bloomfield Hills, MI
Maten is a solid mid-level forward that remains productive around the hoop as both a rebounder and post scorer. Much of his production comes from energy plays and playing with a high motor.

Paul Miller -- 2014 -- SG -- Wisconsin Shooters
6-4 -- Kettle Moraine -- Waukesha, WI
Miller shot the ball well last week and will look to continue the hot start to his July in the Summer Jam. He also does a bit off the bounce as well and likes to take big shots in close games.

Tory Miller -- 2014 -- F -- KC Run GMC
6-7 -- New Hampton School -- Lee's Summit, MO
Miller does a great job attacking the basket and finishing around the rim and also has a decent set of hands with some solid footwork.

Quadri Moore -- 2014 -- F -- Sports U
6-8 -- Linden H.S. -- Linden, NJ
A big with size and skill, Moore will step outside and knock in jumpers or use his soft touch to finish on the interior. A wide-bodied big, Moore can be tough to stop because of his versatile scoring package.

Jared Nickens -- 2014 -- SG -- Sports U
6'6 -- Westtown School -- Monmouth Junction, NJ
The Maryland commit shoots the ball at a high level, especially coming off of screens and can really get hot and get rolling.

Jahlil Okafor -- 2014 -- C -- Mac Irvin Fire
6'11 -- Whitney Young -- Chicago, IL
The top player in the country, Okafor is a force down low and mixes great footwork along with tremendous hands to be an unstoppable force in the low post. Okafor is one of the best post prospects to hit high school basketball in the last five years.

Ahmaad Rorie -- 2014 -- PG -- Team Bradley NW Panthers
6'0 -- Lincoln H.S. -- Tacoma, WA
A scoring point guard with a quick release, Rorie can smoke jumpers from deep and also get some things done using the dribble drive. The Cal commit is fun to watch and can single-handedly win games if he heats up.

Ryan Taylor -- 2013 -- SF -- Full Package Walker
6-5 -- Michigan City H.S. -- Michigan City, IN
Taylor had a big NY2LA Invitational with his ability to knock in three-pointers -- both off the catch and off the bounce -- while also handling some point and defending multiple positions.

Justin Tillman -- 2014 -- F -- Reach Legends
6-8 -- Pershing H.S. -- Detroit, MI
One of the better rebounders in the class, Tillman gets on the glass on both ends and also has a developing offensive skillset. His motor runs pretty high and Tillman has some upside as well.

Karl Towns - 2014 - F/C - Sports U
7-0 -- St. Joseph H.S. -- Metuchen, NJ
The Kentucky commit hits the UA Summer Jam with a big reputation and an even bigger game.  He can score inside and outside, he has tremendous instincts, and a big strong powerful long frame that he can use to do damage on both ends in a variety of ways. 

Romelo Trimble -- 2014 -- G -- D.C. Assault
6'2 -- Bishop O'Connell H.S. -- Arlington, VA
A scoring guard, Trimble will handle the ball at times but is more at ease scoring the ball and hunting for his own offense. A Maryland commit, Trimble can make shots off the catch or off the dribble.

Myles Turner -- 2014 -- PF -- Texas Select
6'11 -- Trinity H.S. -- Bedford, TX
One of the country's premier prospects, Turner has had a meteoric rise this spring and summer from unranked to the top 10. With his combination of length and skill, Turner is a menace on both ends of the floor and can block shots or knock in face-up jumpers with ease.

Isaiah Whitehead -- 2014 -- G -- Juice All-Stars
6'4 -- Lincoln H.S. -- New York, NY
One of the best scorers in high school basketball, Whitehead can get cooking quickly and start knocking in jumpers at a very high level. Isaiah wants the ball in his hands in big moments and can score at a high level in multiple ways.

Stephen Zimmerman -- 2015 -- C -- Dream Vision
7'0 -- Bishop Gorman H.S. -- Las Vegas, NV
One of the nation's premier big men, Zimmerman is skilled enough to knock in face-up jumpers while also crashing the glass and trying to dunk everything around the hoop. Once he adds more strength, he'll be a scary prospect.
