Is his ceiling Brandon Knight?
That's probably pretty accurate based on what I've seen and heard about him. Outside of a trade involving the Bucks picks and Bender or Okobo, I wouldn't do it. I'd be hesitant to trade Melton for him because at least Melton is a good defender who plays within the team concept of the offense and I don't think Smith Jr does that. He's a score first PG similar to Knight and Bledsoe but he doesn't have Bledsoe's explosiveness or defense but he's actually really comparable to Knight. He's as fragile as either of them also, having already had extensive knee surgery at his age. He doesn't make those around him better and despite playing more off the ball with Doncic this year his scoring has actually gone down because he's not a very good shooter either. He shot 39% last season and this year he's shooting 44% but he's also a terrible FT shooter, having shot below 70% in both seasons, 69% in his rookie year and 68% this year. He averaged 2.8 FT attempts a game last year and this year he's at 2.6, which isn't a lot but it's also enough to know that his FT% isn't a fluke from limited attempts.
