So the best way to accommodate George plus a max signing would be to do a sign and trade for Hayward/Griffin then trade for George. In order to do this we could be able to stay above the cap and thus not need to renounce free agents/overseas guys. Since the Clippers would be over the tax anyway, they are a lot more likely to accept a sign and trade than Utah. Here is how it would work imo
1. Trade Bradley, Mickey and Olynyk (signed at around 13.6 MM in his first year) for Blake Griffin
2. Trade Crowder, Zeller, Jackson and picks for Paul George
The roster would look like
1. Thomas/ Rozier
2. Smart/ Brown/ Green
3. George/ Tatum/ Semi
4. Griffin/ Yabu/Jerebko
5. Horford/Zizic/Withey (room exception)
The problem is if we want to extend George too we would need to create additional cap space, which would be extremely hard to do. If we don't extend George he could walk the next year leaving the Celtics with nothing, but if we do extend George we would have to clear so much salary that our bench would be terrible.
