<!-- wp:paragraph --> <p>Some players show up and play well, and others shift the game when they step on the floor. Day 1 at the 15U level had a handful of those guys. You could feel it in the runs, the momentum swings, the moments where everything tilted because of one player's presence. Whether it was scoring bursts, defensive plays, or just controlling the pace, this group consistently found ways to impact winning in real time.</p> <!-- /wp:paragraph --> <!-- wp:acf/evaluation-block {"name":"acf/evaluation-block","data":{"player_evaluations_0_player":["2824972"],"_player_evaluations_0_player":"field_62ab9d62ecf2c","player_evaluations_0_override_profile_image":"","_player_evaluations_0_override_profile_image":"override-player-profile-image","player_evaluations_0_not_in_database":"","_player_evaluations_0_not_in_database":"field_62aba48cecf2d","player_evaluations":1,"_player_evaluations":"field_62aba7547dc44"},"mode":"preview","alignText":"left","anchor":"acf-block-69e333c9db1d8"} --> <!-- wp:paragraph {"placeholder":"Add evaluation here...","className":"text-gray-700"} --> <p class="text-gray-700">Clarke is a true microwave scorer, and we saw that as he provided instant offense with his ability to heat up quickly. Clarke proved to be a confident shooter and scorer on the perimeter, and he was also capable of creating his own shot. He showed flashes of being a dangerous scoring option. When aggressive, he changed momentum in a hurry and his team went on a run from him trying to make plays happen. As his consistency and assertiveness grow, his scoring ability gives him intriguing upside as a spark plug. Solid Day 1 from him. </p> <!-- /wp:paragraph --> <!-- /wp:acf/evaluation-block --> <!-- wp:acf/evaluation-block {"name":"acf/evaluation-block","data":{"player_evaluations_0_player":["2959795"],"_player_evaluations_0_player":"field_62ab9d62ecf2c","player_evaluations_0_override_profile_image":"","_player_evaluations_0_override_profile_image":"override-player-profile-image","player_evaluations_0_not_in_database":"","_player_evaluations_0_not_in_database":"field_62aba48cecf2d","player_evaluations":1,"_player_evaluations":"field_62aba7547dc44"},"mode":"preview","alignText":"left","anchor":"acf-block-69e333c9db27d"} --> <!-- wp:paragraph {"placeholder":"Add evaluation here...","className":"text-gray-700"} --> <p class="text-gray-700">Kinsella made his presence felt with effort and awareness, consistently finding ways to impact the game and just always being in the mix. Kinsella is very active without the ball but also truly looks ot make plays when he has it. He kept things moving offensively while stepping in to make key plays. He's scrappy, competitive, and unselfish, and what really stands out is that he understands positioning and timing. Kinsella's ability to contribute in subtle but meaningful ways makes him a player whose game translates to team success and I am curious to watch more of him. </p> <!-- /wp:paragraph --> <!-- /wp:acf/evaluation-block --> <!-- wp:acf/evaluation-block {"name":"acf/evaluation-block","data":{"player_evaluations_0_player":["2819190"],"_player_evaluations_0_player":"field_62ab9d62ecf2c","player_evaluations_0_override_profile_image":"","_player_evaluations_0_override_profile_image":"override-player-profile-image","player_evaluations_0_not_in_database":"","_player_evaluations_0_not_in_database":"field_62aba48cecf2d","player_evaluations":1,"_player_evaluations":"field_62aba7547dc44"},"mode":"preview","alignText":"left","anchor":"acf-block-69e333c9db2f2"} --> <!-- wp:paragraph {"placeholder":"Add evaluation here...","className":"text-gray-700"} --> <p class="text-gray-700">Harley is a raw but intriguing big man who has plenty of tools to work with. Hartley brings size and presence that immediately affect the game, and he's always around the basket, making things difficult down there. He rebounds well, protects the rim by going straight up, and uses his length to alter shots. Now it is about getting the coordination together so that those blocks attempts turn to points the other way and rebounding opportunities. Hartley is still developing his offensive game, but the foundation is there. As his feel and skill set grow, his physical tools give him the potential to become a true difference-maker inside and he's a player to get on more radars soon as he had a solid day 1. </p> <!-- /wp:paragraph --> <!-- /wp:acf/evaluation-block --> <!-- wp:acf/evaluation-block {"name":"acf/evaluation-block","data":{"player_evaluations_0_player":["2817936"],"_player_evaluations_0_player":"field_62ab9d62ecf2c","player_evaluations_0_override_profile_image":"","_player_evaluations_0_override_profile_image":"override-player-profile-image","player_evaluations_0_not_in_database":"","_player_evaluations_0_not_in_database":"field_62aba48cecf2d","player_evaluations":1,"_player_evaluations":"field_62aba7547dc44"},"mode":"preview","alignText":"left","anchor":"acf-block-69e333c9db35c"} --> <!-- wp:paragraph {"placeholder":"Add evaluation here...","className":"text-gray-700"} --> <p class="text-gray-700">Kurth plays with a high IQ and a team-first mindset, consistently making the right reads, and he did a ton of things that stood out for me personally. He can knock down shots when open and keeps the ball moving without over-dribbling, which gives you an understanding of how he operates. Kurth also understands spacing and timing, and those things were quietly impacting the flow of the offense for Rocky Mountain Rebound in a fast-paced game. He looked to be a reliable presence who doesn't force action but still contributes, making him a player worth tracking as he continues to develop. I am excited to see if he continues that play on the weekend, as he stood out on day 1. </p> <!-- /wp:paragraph --> <!-- /wp:acf/evaluation-block --> <!-- wp:acf/evaluation-block {"name":"acf/evaluation-block","data":{"player_evaluations_0_player":["3564573"],"_player_evaluations_0_player":"field_62ab9d62ecf2c","player_evaluations_0_override_profile_image":"","_player_evaluations_0_override_profile_image":"override-player-profile-image","player_evaluations_0_not_in_database":"","_player_evaluations_0_not_in_database":"field_62aba48cecf2d","player_evaluations":1,"_player_evaluations":"field_62aba7547dc44"},"mode":"preview","alignText":"left","anchor":"acf-block-69e333c9db3c5"} --> <!-- wp:paragraph {"placeholder":"Add evaluation here...","className":"text-gray-700"} --> <p class="text-gray-700">Wagner consistently made plays on Day 1 as he was one of my favorite watches for 15U. He's attacking the rim, moving without the ball, and takes open shots when they come his way. He brings energy and versatility, contributing across different phases without needing the ball to be effective. Wagner also shows coordination and athleticism that translate on both ends, and he provided a spark for the team, which led to their 1-0 record against a bigger Elevation squad that battled. Wagner scored a few times but made impactful plays as he showcased a well-rounded game. Have to see more Wagner. </p> <!-- /wp:paragraph --> <!-- /wp:acf/evaluation-block -->

Some players show up and play well, and others shift the game when they step on the floor. Day 1 at the 15U level had a handful of those guys. You could feel it in the runs, the momentum swings, the moments where everything tilted because of one player's presence. Whether it was scoring bursts, defensive plays, or just controlling the pace, this group consistently found ways to impact winning in real time.
