Ja is significantly better than all 3 of them. It'll just be easy dump offs for him like he got with Russ. Couldn't get those in New Orleans since Lonzo can't dribble and is allergic to the paint. Will have more room to operate in there too since JJJ will be on the perimeter a bit more than Zeeon was.
Probably ends up giving you like 14 and 8 a game or something like that. I'm not saying he's some force or anything like that, and I do think he's a downgrade from Valancunias, but he'll play his role decently.
