I only have highlight videos of Porter and Bagley to go on, but Doncic's Eurobasket performance basically means one of those guys either needs a NPOY or best player on a final four team season to knock him off, I think. Even if Doncic struggles in a bigger role this season, he's playing at a higher level of competition than the NCAA guys, so he should get some leeway.
Adel will pretty much get drafted or not based on his 3P and FT% I would have thought. If Louisville lives up to expectations defensively, and NBA teams think he can shoot the 3, it's hard not to see him sticking in a 3-and-D role.
I don't know how scouts feel about Landale but I just don't see his game as fitting in the NBA right now. 5 years ago, sure, but today 4/5 men need to be rim protectors or long-range shooters, preferably both, and he is neither right now. He's fantastic in the post, but he's not going to be able to score with that in the NBA and I don't know who he guards - Markannen made him look pretty bad in the tournament last year. I do rate him, I think he's a potential Boomer down the line, and if he eventually added a 3-ball and some straight-line driving and passing on the move, maybe he'd get an NBA look later. I don't see it happening this year, though.
