Expert Analysis
Robbie Hodin | Prep Hoops Scout
UCLA, Minnesota, BC, and many others were in the gym to watch Costello, one of the fastest stock risers of any 2026 in the country. The 6-foot-10 forward continues to develop his handle and is really beginning to see his dribble moves come together. The shot has always been there, but he’s starting to get it off in different ways, which opens up his offensive skillset and versatility. Defensively, he’s getting stronger and continuing to understand how to use his length and athleticism. This will be a big year for Costello’s development and the HM offers will probably keep rolling in, though I’m sure he’s close to committing somewhere.
