I guess the 'conspiracy theory' here would be to advertise him with little intrigue because Portland wants him over Scoot and hopes to lower his stock.
But imo, he does not look as sharp as the Thompson twins or Scoot in their workout videos.
Certainly, workout footage is quite selective but the way I see it, you put the pieces together and this practically confirms why he may be shy to attack the rim (he's too slow).
Meanwhile, his release is somewhat low. Because he is tall and lengthy enough, it won't get blocked as often. The idea is that lower = faster release. He's quick on the draw and that's why he gets his points.
But....against tough competition, he hasn't performed as well and I think his release may have something to do with it. Unlike Banchero or Tatum, who both performed well against ranked competition and who both have higher releases, I think you're going to see the limits of his offense.
He'll be streakier if he feels that he has to rush what is already a rushed shot.
A comment above stated that Reggie Miller had a low and quick release in an attempt to draw comparisons but Reggie's release was higher than Brandon's. Maybe if Brandon wants to be like Reggie, which he has the talent to be like, he'll adjust his shooting form just a tad bit but for now, I can see why it might not work as well in the NBA.
