Celtics get Ja and Jock. Jock helps fill their center position and is a sweetener. Second round pick to ofset the loss of Sam Hauser to make contracts work.
Grizzlies get Simons who could resign and be a positive young asset or be an expiring contract. Sam Hauser can shoot and is here to make salaries work but is an added bonus.
This is purely Fun and hypothetical I would not want this for either team. Just seeing what Ja could go for on as many teams as possible.
