Brown, White, Porzingis, Hauser, Pritchard
For
Giannis, Lillard
It technically works though Boston would likely need straight minimums and some reduction to stay below 2nd apron. And maybe you do that with Holiday though I'd like to keep him in that trade scenario.
You hope Tatum and Lillard are back for playoffs this year. By taking in Lillard you give the Bucks a lot of value that other teams can't, which can help bridge the gap on why they might take Brown as main piece for Giannis.
