So Danny trades up to 5 firsts, Sullinger and if necessary, Isaiah Thomas. He is able to work a multi-team deal that gets us a top 5 pick - Winslow, and also move down a few slots to grab Kaminsky.
If I were Love or Monroe, I'd want to play with that group.
If I'm understanding you, the deal would (or at least, could) be:
Sully + Thomas + five first rounders for Winslow + Kaminsky?
I think that offer would arguably be too much for DeMarcus Cousins, let alone Winslow and Kaminsky.
I was trying to make a point. We could make a bold move, which could leave us with a scenario that could then attract some interesting free agents. I think it would be too much too, but it shows what is feasible. Something through this draft could leave the franchise in better shape than signing a pretty good young player to a huge contract. Towns, Winslow or Russell could be tremendous players. And you haven't spent any money yet.
So I'd rather go with Winslow, Kaminski and tons of cap space. Cousins is great but will never be the top player on a championship team.
