At this point in the season

Just start Kuminga at the 3 and play him 36 minutes a game until traded or the season ends.

Everyone needs a true sample size of what JK is or isnt. Without a crazy trade, contention isnt in the cards this season. Switch him out or let him run.

If he's great, marvelous. Trade value is up OR you keep him in the lineup. If he sucks, there is 30 odd games of data to draw from without minutes being jerked around, and him as the de facto #2 option. Either way fans and detractors have their fill.
