Ja for Garland, contract for contract. Straight swap. Grizzlies get a second cause the Ja Morant Potential is much larger than that of Garland.
Don't see this working for the Cavs but Garland has been in rumors for a while now so there is that.
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.
