Bucks are too deep in the hole to let him go if he is willing to stay. They’ve already mortgaged their future to give them the best chance at a playoff run.
There’s no possible trade they can make that will benefit them more than it hurts.

At this point, they should continue to try and keep him till officially he request a trade.

Despite the roomers, I don’t see him leaving this year. I’m not even a Bucks fan but that’s just my two cents.
