The thing that Bilal has that these guys dont is elite athleticism. It's what's going to allow him to leverage all his other skills.Yeah... the reason I think it should be taken serious as a worry for him is that it's not just in SL that this happened. It was happening in his team in France too. He was not relied to create offense or even finish offensive possessions. And he looked similar to what you and Elizah are describing... some flashes of great play... but then he would just float...
BTW, don't know if you watched the FIBA U19 games last week... but Risacher is WORSE than Bilal in that respect. He floats and disappears even among players same age as him. It was shocking watching him and reading mock drafts having him top 3 next year.
I ended up being pretty high on Bilal at the end of the pre-draft process, but SL has definitely made me even higher. I think he's closer than I gave him credit for.
