I'd take Green and Brooks over Mikal, CamJ is mostly irrelevant IMO.
Cam has struggled to stay healthy. He misses 25-30 games a year. He found a nice landing spot in Denver where Gordon could guard the better wings while he was more of a 3&D guy but he got hurt before Christmas. He's shooting 43% from 3 but only producing 11.7 ppg after scoring over 18 last year. He works well in the right system and I think we'd have that here with Mikal and Williams also in the front court, supposing the choice of Cam and Mikal. Mikal is averaging 17 PPG in NY, removed his Brooklyn stats since he wouldn't be the guy here. He's doing that on 37% from 3 and a very good defender who doesn't do the stupid stuff Brooks does, while being a better defender on wings also.
It's close. All things considered it's probably too soon to make a fair comparison since Jalen has played in 3 games, none with regular minutes. So this could be revisited in March when we have a better idea of what he brings.
If the picks were involved though I think it's a no brainer to go with Mikal and Cam.
