Man, I think there are probably quite a few GMs who are glad they didn't pay for or be in consideration for Durant. It's awesome he's ready to let someone else (Booker) be the face but IMO he used it as a chance to reduce responsibility for failure. Aggressively. Still talented and will be able to shoot over people until he's 80 and could still play a great supporting role for a contender but looked completely over the hill. Should be traded for what can be salvaged.
Beal is a talented-at-times scorer who, against weak teams, in his prime, could do well. The playoffs, when your older are no time to learn how to compete, play as part of a system or play defense. Has to go.
Booker won't be traded, he's the face. He's better than Beal as he has grit and a much higher floor and ceiling but he's gotta learn how to play team D.
Nurk was decent but is used to playing with talented passers and team ball...Booker and Beal mostly heroball. Nurk also doesn't have what it takes for the playoffs, he's been outclassed in ost every series I've ever seen him in while with Portland...including making Ayton look good at times.
Don't fire the coach, dude is good.
