Liam Robbins is. Carr has a chance, so does Mashburn, Gach, and Ihnen.
Gach, Carr, Liam and Ihnen all have an outside chance at making the league but ultimately I don't think any of them will.
Ihnen has a shot but the same way Charles Buggs had a shot meaning we are only basing this off his physical attributes and skill, not what he has done on the court. He has a long ways to go.
With Liam it will be an uphill battle because the NBA has moved away from traditional centers and has opted for smaller lineups and the centers who do play are mostly above the rim athletes who get used as rim runners, rim protectors and lob threats like Javale Mcgee or Cauley-Stein which isn't Robbins game. And if he was NBA caliber, I'd like to see him put up better numbers at Drake.
With Carr, it will be an outside chance for the same reason it was with Nate Mason, just doesn't have the combination of size, speed and quickness to translate to the NBA level. Same for Mashburn but Mash needs to get to a Carr or Mason's level before we even think NBA is a chance. I actually think Gabe has a better chance than Mashburn right now and thats not saying much.
I do think Gach has the best chance, he just looks most like an NBA player with his size for his position, athleticism and one on one game. Watching his highlight tape, and of course I know it's just a highlight tape, but he reminded me of Zach Lavine at UCLA. Lavine is obviously a better athlete and also was a better shooter, but just his game and how Gach could get to the rim and finish reminded me of that. Obviously not saying Gach will be anywhere near Lavine, just that his game reminds me most of an NBA game.
Still though, he needs to make big improvements and thats just to sign a two way contract. Amir as a freshman was better than Gach as a sophomore and it took Amir two more years just to go undrafted and sign a two way contract and Gach has a ways to go just to get to the level Amir was at junior year which didn't even get him drafted.
With Amir and Oturu, I always felt that the chances of them making the NBA were above 50%. With Gach, Liam, Carr and Robbins, the chances are definitely well below 50% but not outside the realm of possibility.
