I would blame Josh for wasting our chance with the U18 last 2022. We had Mason then, e.
Also the fact that he relegated Edryn Morales and Bonn Daja to playing just the 4 and 5 spots in last year's U16, despite them having skillsets sufficient to play the 3 (and even 1/2 on Morales' part). We did qualify for this year's U17 WC thanks to a good gameplan and good physicality in the Asian level.
And he's a bit too much like his dad. "Small ball" without much a change in roles and/or skillsets in the key small ball positions, which is 4 and 5. The 4 and 5 just screen, roll, grab offensive boards, or if they can, shoot. In small ball, your 4 and/or 5 are supposed to be more versatile on offense and more importantly, defense. Your small ball 4 is a wing (LeBron, Tatum, KD, Melo), and your small ball 5 is either a tweener (Draymond Green) or a bigger 4 (Chris Bosh, Amar'e Stoudemire).
