I'm having a hard time getting excited about this draft, and that's pretty rare for me.... To be a star, a player needs to have a combination of physical profile, advanced skills and competitiveness, and few players in this draft seem to really put that package together.
Overall, I think Topic, Holland and Knecht can be high-impact players for various reasons.
Sarr will work as a rim-runner and rim protector who can maneuver enough to score in some face-up situations, but I don't believe enough in his shooting touch to think he's really going to be versatile offensively.
I like Dillingham and think he's more versatile off the dribble than Colin Sexton, though Sexton's relentless motor, downhill drive and effort on defense probably makes that comparison close to a wash.
Both Cody Williams and Kyshawn George are interesting as 6'8" wings with shooting touch and decent ball skills. Williams is craftier and a more opportunistic scorer right now, but both of them need to work on their bodies and play with more physicality to be able to really force action. Their lack of burst leads to them being too passive, imo.
With Buzelis too, his lack of physical profile is holding him back. It becomes a question of whether he can add enough strength and quality weight to get where he wants on the floor. The comparison to Franz Wagner isn't going to work unless Buzelis can add 15+ lbs. Then there's the hope that he'll be able to shoot the ball better than he's shown in the G-league.
Rischacher plays with consistent energy and really runs the floor, but his lack of wiggle and inability to beat defenders off the dribble consistently probably make him more of a glue guy. Someone else is going to need to buy him some space or an open lane to drive. With Salaun the hope would be that he can develop his handle and be able to shoot off the dribble. Otherwise, he's going to be another floor-spacer type.
I think Tyler Smith is a legit lottery talent, who has more athleticism and straight-line burst off the dribble than he normally shows in G-league pickup games. Still, he's more of a complementary stretch-big who will mostly spot up. His old-school comp might be a Sam Perkins type.
If Filipowski can add some more strength to his frame and become a consistent enough shooter, he becomes a starter-level big worth drafting due to his versatility and playmaking. Not sure if he's ever going to be long or bouncy enough to be a real rim deterrent, but he can make some plays on offense like Olynyk. He's not as fluid or skilled as Sengun. If we look at Jusuf Nurkic as an example, Nurkic has career averages of 12 pts, 9 rebs and around 2.5 asts. I think Filipowski can likely do that with a few more passes and 3s, depending on how he's used.
I'm having a hard time getting behind Stephon Castle. He can defend and pass the ball, but his athleticism is going to look average at the NBA-level and he's already a pretty reluctant shooter. If Brice Sensabaugh will continue to work hard on defense and improve his conditioning, I think Brice is a better prospect.
I would draft Ulrich Chomche, make a bet on his physical tools, and see if he has the raw competitiveness to make himself into an impact player (similar strategy to drafting Rudy Gobert).
