I really don’t see the problem with his height, he is long and his standing reach is high. You don’t block shots with your head. Biyombo isn’t undersized, his standing reach is a tenth of an inch shorter than Dwight Howard’s.
I see bust potential in Brandon Knight and Jan Vesely. Knight was unproductive in college, is a poor pick and roll player, and has some physical limitations. I just don’t see his game translating to the NBA. I think that people overrated his shooting ability. He is known for his work ethic, so it may improve, but he has a low release point and struggled to gain separation from college defenders, and didn’t put up great numbers in college. There is also no guarantee he will ever become a great play maker.
In Vesely, he just seems like a classic tweener. If he was a good rebounder, than I could see him being a great 4, but I don’t think he has the skills to be a starting 3. He isn’t a great shooter and ball handler, and a player his height will struggle with perimeter defense. I hope he does well, though, because he seems like a great transition player to fit with John Wall.
