For some reason, I'm not worried. Chris Paul is old, injury prone, and fading fast.
Deandre Ayton was always a guy that had people at, "wow! he's going to be great when he develops!" Then he's never changed. Deandre Ayton 5 years into the league is the same as rookie Deandre Ayton. That's great, but it's not scary.
Kevin Booker is awesome, but he's streaky.
Durant is also old, injury prone, and fading fast too. To go with it, Luka has been a Durant killer the past couple of years. I don't know what it is, but Luka gets in Durant's head. Durant plays down against Luka and the Mavs, and Luka plays up against Durant no matter which team he's on. I think it's because Durant is used to being the best scorer on the court his whole career until he started getting slapped in the face by Luka every time they met. Durant crumbles around Luka.
So we only need 2 defenders for Durant and Booker, and we've got them - Bullock on Durant for length, Green on Booker for speed. Green might be the only guy in the league as fast as Booker.
I think Christian Wood / Maxi Kleber is a better 1-2 punch than Ayton / ???Jock Landale???. Wood is a little better offensively than Ayton. Ayton is a little better defensively, but on the switch, I think Kleber can absolutely neutralize Ayton. Maxi can take him out of the game.
Lastly, the Suns gave up their second best player to get Durant. Mikal Bridges is gooooood. That loss is going to hurt them more than a lot of people are thinking.
