O’Sullivan is a player that I am extremely high on as he looks like one of the bigger developmental jumps in the class right now the last time that we saw him. In fact, every time we see him he looks vastly improved and it’s the versatility that does it for me. He’s a strong-bodied wing who spaces the floor, and moves naturally without the ball. He can put the ball in his hands and finds ways to flash in the offens like when he hits the midrange shot, gets down on the blocks and he layers the offense. The ball seems to gravitate toward him because he constantly puts himself in the right spots. With the way he’s trending, meaningful varsity minutes feel inevitable this upcoming season and is a player that I’m sure we hear a ton about this year. He earned his spot in the rankings.
Jack looks like one of the most improved players in this class right now as he’s playing high level ball and was a big reason that his team went undefeated on the weekend. Jack is a well-rounded offensive player with plenty to his game. He has face-up, moves without the ball to open spots in the defense and extends the defense with his jumper. He was constantly hitting mid range jumpers and he’s a big body that moves well and connects from everywhere offensively. He lit it up in multiple games and the ball seems to always find him. Jack should get varsity minutes this year if this is how he’s playing in the summer. Stock boosting day for him as one of the top standouts of the weekend.
Sullivan is the real deal, and that was on display throughout the day. He has good size at 6’5, but he has wing/guard skills which makes him a dangerous weapon. He was making play after play, and is a player who pops and you gravitate towards when watching. I like the fact that he got out in transition and showcased him as a facilitator, but also had spurts where he just wanted to score. He’s a sniper from deep that can space the floor and he’s a player that I expect to get varsity time even as a freshman. He’s a 2029 worth watching.
O’Sullivan is impossible to miss on the court with his dominant size and length. He makes his presence felt on the defensive end, showing excellent positioning to grab rebounds and block shots, while working hard down low to secure points in the paint. His combination of effort and natural tools already make him a matchup problem. Looking forward the intrigue with O’Sullivan lies in how he continues to grow into his frame and skill set. He’s already capable of stepping out to shoot from long range, but the next step will be honing in on his mid range and three point consistency. On top of that further developing into an absolute defensive force could make him one of the most complete big men in his class. If he continues this trajectory, his ceiling is sky high
O’Sullivan has been one of the toughest matchups all weekend, leveraging his size and length to dominate the interior. He’s been a force on the glass, pulling down rebounds and creating second chance opportunities, while finishing strong around the rim. What makes him stand out even more is the growth in his perimeter game, where he has been stepping out and confidently hitting shots from beyond the arc
