Neat idea. It's still difficult, arguably just as difficult because you'd need to send Utah at least $23.7 million in outgoing salary. What you'd want to do is just use cap room to acquire/extend George, sending as little in salary as you need. So Rozier and future picks would be about enough if we let Olynyk walk. Then use the cap room, because any excess cap room after extending George would just go to waste, since cap room doesn't count for matching salaries.
Now you have to get to $23.7 million, from Crowder, Smart, Bradley, and Smart. Bradley+Crowder+Brown is only $20.5 million, so you'd have to add Smart as well.
Would Utah do Bradley, Crowder, Brown, and Smart for a S&T for Hayward? I'd have to think so. The roster would look like this:
IT
George
Tatum
Hayward
Horford
Zizic
Room-level exception
2nd-rounders and minimum salary players.
So that's an elite core four, with two rookies who could hopefully provide quality production, but the roster falls off really quickly. It wouldn't be completely unaffordable next year, however, so that's a good thing.
