Knight will be in the league due to his offense--he's a ready-made NBA offensive player and his college scoring numbers should carry over. He's a combo SG who can pass some along the flow of his points. That's pretty much it. He does have some real bust potential, I believe, because he doesn't do anything else besides score on the court. But he's riding some real momentum upwards in the draft. He might need the right team, much like Jennings had with the Bucks.
Terrence Jones's offense is what's dragging his stock down, and I do agree--he's just a very ordinary offensive player, and he might even be a better offensive player in college than what he'll be in the NBA. Meh passing ability. I personally think the highlights to his game are his rebounding ability and his ability to make defensive plays, and this should translate quite well to the NBA. He's not very tall and he's quite a widebody, however, so these things might not translate as well as when jumping jack athletes do them. So there's questionable upside, but he should be better defensively than offensively in the league.
I'm just not sure about Motiejunas. He's a definite project in the league, and the only thing that's really good about him is his offensive upside--there's real potential here, and he also has a very good chance of reaching it given that he produces numbers at the EuroLeague. But everything else is just not NBA material, and that could very well sink him.
Darius Morris's one intriguing, elite asset is his passing/ballhandling--it's at an elite level among college athletes. But I really, really, really think he needs another year and there's bust potential--that's the only thing he's good at, and his work on the other end of the court is very poor. His offense, meh to begin with, might look even worse in the NBA.
Kemba Walker is a NBA viable candidate, particularly on the offensive end. He's an excellent scorer at the college level, and while there will be a dropoff to the NBA he's still a very good scorer at this level. Not a pure PG at this level, but can definitely play PG full time, has the court vision. Can operate in both scoring and passing mode, I personally think. Also a very good disruptor, racks up tons of steals. He's really NBA ready, there's little bust potential with him. His height might be a drawback to some, but he does more than enough and there's quite a few waterbugs in this league, he'll fit right in and then some.
I like the very idea of D.J. Kennedy--the guy is a decent rebounder and passer in the league, he can make some defensive plays and he has an OK shot of reaching this sort of potential. His offense is terrible, but he should look quite better in the NBA than at college. As a versatile fill-in-the-blanks type player, he can make it for sure.
Iman Shumpert is the exact opposite--his offense looks NBA-ready, he has real NBA PG skills and he can wreak havoc defensively, and those look really tantalizing at first glance. But there's real bust potential in spite of that--all of those skills are up-and-down, as he's turnover prone, prone to gambling and his overall shooting ability needs improvement. He's one of those tantalizing NBA prospects that come out every now and then, but might end up doing noting in the league.
Jereme Richmond made what I thought was a very dumb choice to enter the draft, but it turns out scouts are still enamored with his HS play and thus have dubbed him as a second round pick. Richmond rebounds the ball like a lotto pick at the SF slot, but that's about his only bankable skill at the amount. He appears to have decent court vision as well, but his offense and defense appear to be extremely terrible. There's bust potential, but given the miniscule talent he displayed, it's not as much as you would expect--he does have a chance as a rebounding small forward, but I can't help but think of Rodney White part deux.
SUPER smart decision by Perry Jones. He didn't give scouts a whole lot to work with other than marvel at his physical tools all season, but now he can build on the two things he shows ok potential in--current scoring and rebounding. Make himself more viable as a prospect on those two fronts.
