Too early to flip Crowder. He's young, cheap, hard working, good character, had an instant impact on the team and might be a keeper. I have faith that as much as Danny likes to deal he knows which chips to hold onto, it's not like we're hurting for mediocre picks or assets for the coming rebuild.
Turner seems to be an integral piece to this year's team as well and on a good contract. Pretty much a known quantity and less attached to him as a Celtic but I doubt Stevens would be happy to see him go in a fire sale.
And +1 to the point about not helping the Clippers this season. If anything we're subtly trying to push them down the playoff ladder for a better pick, not give them a boost. Rivers deal included.
