Jonathan is seen as a "bust" by many, and thats very reasonable. But a 6'10 beast that can play great defense on a minimum seems like a great trade asset. The lakers have been aggressive in trying to get herbert jones when the Orlando magic might be able to just hand him away for alot less. They can also maybe dump a bit of cap in a 3 team trade with the clippers. Even the nuggets should be trying to get him after losing peyton watson, since they don't really have the cap or assets for a bigger move.

TLDR: He's cheap and a great defender that would be an amazing piece you can just toss into a team and see great results. Why isn't he on the market? I haven't even heard the magic upright say "no" to a trade offer because there aren't any.
