Summer provides a clear picture for initial 2025 On3 50

On3 has released its first basketball player rankings for the 2025 cycle. This 2025 On3 50 rankings release is the first of what will be a handful for the class.

Even with a gap in the playing seasons, travel ball ending in July, and high school seasons not starting until mid-October, that does not mean evaluation has been put on pause. This first ranking for the 2025 class was heavily impacted by freshman season play as well as spring and summer travel ball evaluations.

On3 is starting with 50 prospects in the class. There will obviously be a new No. 1 player here, but also three five-stars in the initial 2025 On3 50. The most pressing question in creating these rankings is who is No. 1?

Cooper Flagg vs. Cameron Boozer

Cooper Flagg is a 6-foot-8 wing forward from Portland, Maine, by way of Montverde (FL) Academy. Cameron Boozer is a 6-foot-8 power forward from Miami (FL) Christopher Columbus High.

This conversation lasted throughout the summer and will most likely remain over the next three years. Flagg is a rangy wing who some compare to an Andrei Kirilenko archetype. He has high-level natural instincts on the defensive end and shot 42 percent from three with the u17 USA men’s basketball team en route to a FIBA gold medal this summer. Flagg led the team in rebounds, steals, and blocks per game.

Boozer, the son of former NBA All-Star Carlos Boozer, averaged 22.5 points, 12.2 rebounds, and 4.2 assists through 13 Nike EYBL 15u Circuit games. His Nightrydas team also won both head-to-head matchups against Flagg this summer. Boozer is also very young, a full seven months younger than Flagg.

This is more of a “1a” and “1b” situation than it is a one and two deal; however, rankings deal in absolutes. While Cooper Flagg got the No. 1 spot on the inaugural list, as I mentioned above, we do not expect this conversation to end any time soon.

Grading the On3 50 for 2025

The basketball player rankings scale is as follows: Five-star prospects have grades 98-100, four-star recruits have grades 90-97, and 80-89 grades are for three stars.

The first three prospects are five stars with a rating of 98 or higher. The rankings for current cycles will be updated on a regular schedule throughout the year, with 20 five-stars by the final ranking of a cycle. Our goal is to assess a prospect’s long-term potential in college basketball, ultimately manifested by the NBA draft.

Let’s get into more of the storylines surrounding the On3 Top 50.

Three five stars in the On3 2025 rankings

In going through the rankings, we felt there was a clear line of demarcation between prospects Nos. three and four. These three are the ones we expect to hover around the top spot for the next three years.

We went over Cooper Flagg and Cameron Boozer earlier, but Isiah Harwell is a name to familiarize yourself with as well. He is a 6-foot-5 wing guard from Pocatello, Idaho, by way of Mount Pleasant (Utah) Wasatch Academy.

Harwell averaged 18 points and eight rebounds as a freshman at Pocatello (Idaho) Century High. Harwell is a shot maker and a shot creator with great positional size and good athleticism. Playing up two grade levels with the Utah Prospects on the Adidas 3SSB 17u Circuit, Harwell averaged 12.7 points, dished out almost 2.0 assists, and knocked down 1.2 threes per game.

Harwell’s father, Ron, was a D-I hooper at Idaho State in the mid-90s. Ron Harwell was a 6-foot-2 guard who averaged 14.5 points, and 2.2 steals in his senior season.

Wing-heavy class thus far

Seven of the top ten players in the initial 2025 class are labeled as either shooting guards or small forwards. Five-stars Cooper Flagg (small forward) and Isiah Harwell (shooting guard) are Nos. 1 and 3 on the list.

High-flying Jamier Jones comes in at No. 5 overall on the list. Jones, who transferred this summer to Bradenton (FL) IMG Academy, is a lanky and explosive small forward who had an efficient summer leading his Florida Rebels program in scoring. On the Nike EYBL 15u Circuit, Jones shot 54.3 percent from the field.

Efeosa Oliogu (No. 6) is the highest-ranking Canadian prospect in the rankings. The small forward from Toronto (Can.) United Scholastic Academy played up two grade levels this summer with the Canada Elite program on the UAA NExt 17u Circuit. The smooth Oliogu averaged 16.9 points and shot 40 percent from three.

No. 8 Elzie Harrington averaged 13.2 points, shooting 48 percent from the field for Bellflower (Calif.) St. John’s Bosco during his freshman season. Harrington has positional size and a smooth feel with confident shot-making tools.

Jalen Haralson comes in at No. 9 in the 2025 class. The 6-foot-7 shooting guard played up in grade level for the Indy Elite program on the Nike EYBL 16u Circuit. He led his team in scoring at 13.7 points with a 51.3 effective shooting percentage. Haralson is at Fishers (Ind.) High.

Rounding out the top ten is No. 10, Meleek Thomas. Simply put, the 6-foot-4 shooting guard is wired to score. He averaged 16.5 points on 40.9 percent from the three for the New Heights Lightning program on the Nike EYBL 15 Circuit. Thomas is at Pittsburgh (Pa.) Lincoln Performing Arts.
