Not Wagner and Kispert. They are developed. Which also limits their potential somewhat. Barnes comes in ready to play NBA defense with his tools and having gone to a school that plays NBA switch defense primarily. Giddey is another one of those Aussie players that are going to be prepared as well as possible. Look at LaMelo, it really helped him a ton. Sengun has a long way to go. No way does Walton play him with where his defense is at. No way.
Wagner and Kispert aren't going to be projects but I think they'll struggle against the physicality of NBA players.
Giddey has a lot of potential but the concern I have for him is similar to how I felt about Lonzo Ball. It's hard to be a primary ballhandler and create for other players if you're not a threat to score. Guys will just play off you and dare you to shoot it.
I've already talked about why I'm not high on Barnes. He's got a long ways to go with his scoring before he belongs on an NBA floor. There have been success stories in the past and maybe he's got some of that Draymond Green energy where he's so good at everything else that it doesn't matter that he can't score but I think he's going to struggle, especially if he goes into a situation where he's hyped up as a cornerstone player.
Kai Jones is one of those players who is more of an athlete than a basketball player to me. He's a catch and finish big with poor defensive fundamentals. We've already wasted half a dozen first round picks on similar players and none of them panned out.
And Sengun doesn't look like an elite NBA talent to me. I think he's an elite international player who is a fringe player in the NBA where the game has moved more to the perimeter and bigs need to be able to do more than play in the post. He can handle a little bit but not well enough for it to be more than a novelty. And even when I look at his highlights most of what he's having success with right now is going to get shut down against NBA strength and quickness. Maybe I'm way off here but he's not a gamble I'd be willing to take.
