Not saying you're wrong, but curious which you think those are?
Rick Majerus used to favor the better athletes with elite potential vs. developed college players who didn't have as much upside. He said players will learn to shoot once they get in the league. He made a point to call out Anfernee Hardaway as a better prospect than Calbert Cheaney in one draft. Believe it or not, that was a real debate in the 3 - 5 range of that draft. A player like Iman Shumpert is a good example. He was an NBA athlete and defender who learned to shoot. Same with Kawhi Leonard.
There are polished players who can shoot and score in college, but if they can't compete physically at the NBA level, they can't really stay on the floor. Karasev is a guy who risks falling into that category. Bennett too to some degree, unless he can stay light and really play on the perimeter.
In terms of potential there are several players that stand out to me:
* Noel - elite athleticism, feel and quickness for his size; people compare him to Larry Sanders, but he should be a significantly better player than that simply because he's faster and has better feel and timing. He'll make big plays at both ends.
* McLemore - great athlete and stroke, but best suited to roam the perimeter like Ray Allen; a supporting player (3rd option).
* Oladipo - he's really good and starting caliber, but how much more can he develop from here? (3rd or 4th option)
* Steven Adams - one of my favorite prospects in the draft; excellent size, speed, natural athleticism and feel. Good physicality. Should be comparable to Andrew Bogut and potentially even Andrew Bynum.
* Porter - he's a good player, but he has to work on his athleticism to be able to do the same things at the NBA level; also a complementary player (3rd or 4th option); he'd do well to keep developing his ball skills and pattern his game after Hayward.
* Burke - could be Chris Paul lite, but how much more can he improve given his physical limitations (size/speed)? He'll do okay simply due to NBA spacing, but won't carry a team unless he somehow finds another gear.
* Len isn't quick enough to be a #1 option; he should gain weight/strength and pattern himself after Roy Hibbert (2nd option).
* McCollum - can do what Lillard does away from the hoop and has a better mid-range game, but can't get to the rim like Lillard; he can do a lot of things DWill does if he works in a system. Oh and this evening's version of Gary Neal.
* Cody Zeller - 2nd unit guy on most teams unless he's going to start next to a dominant center (like Splitter next to Duncan)
* Shabazz - needs to keep improving his conditioning and his stroke; needs to understand he's not going to be the guy at the NBA level and he needs to pass and defend; maybe he's a Caron Butler (3rd option)
* Olynyk can make it as an inside/outside PF with range to 20 feet, and could be a starter depending on the situation. He'd start in OKC.
* Tim Hardaway Jr. can be a good 2-way SG. Same with Glen Rice Jr. Those are pro athletes with pro skills (3rd or 4th options)
* Giannis Whatsisname - He's got a long way to go and is really like a high school senior, but he's the most interesting player to me in this draft after Noel. He should end up being 6'10" with a handle, passing, and good defense at a minimum and real upside on the offensive side.
* Dieng looks like a defensive player and borderline starter like Dalembert. But his feet are a bit too slow to be much more than that. Maybe he becomes a poor man's Ben Wallace.
