I haven’t kept up with Yam, but Juhan is staying active. He’s just 19 and starting on a higher tier French team. This review makes him sound like a mashup of Langford and Schroeder right now, but he’s got time to develop his game. https://www.celticsblog.com/2021/11/15/22775300/checking-in-on-boston-celtics-nba-draft-and-stash-juhann-begarin-45th-pick
He needs to learn to pick his spots with his speed instead of going 100mph all the time, but Nesmith is still struggling with that himself. Romeo is more in control and knows where to be, but he’s not as aggressive putting pressure at the rim. Slowing down and playing under control will help him creating for others and improve his assist to turnover rate.
He’s raw, but still shows potential even though his game looks more street ball than NBA.
