If those are only 3 teams then the price to get Butler won’t be that high.
What could the Clippers give up? Say 2 expiring contracts in Wes Johnson, Marjanovic, the rookie Gilgeous-Alexander, and 2 future firsts maybe. A starting 5 of Bradley, Butler, Harris, Gallo, and Gortat could be appealing with Butler handling the ball a lot. Could be good news for the Clippers pick that is lottery protected.
For the Knicks maybe Noah’s big expiring contract, rookie Knox, and 2 future firsts?
Would the Nets be willing to trade future firsts ever again? Lol
