I honestly don’t think any team in the west can stand up against Phoenix right now :( Denver does not have a deep enough roster that can actually support Jokic adequately. For Lakers, admit it or not, Davis is a liability that can get a 6 month injury anytime he is on the court, Lebron is old (even though he is still balling, but his reflexes regressed and he cannot do it all when he is 38) and the rest of the roster is good but not deep enough. Memphis has a good young core but is inexperienced. GSW and Kings are good possibilities but GSW is not the one back from 2017-2018 years and is more prone to losing it all especially against a roster which resembles the one from their prime years. For Kings, refs can pull up another 2002 anytime soon just to get Phoenix-GSW matchup at the end of the day.
At the East, maybe Boston or Bucks can go against them since Boston has good defensive system that can shut down a good offensive team like Phoenix and Bucks for having a Shaq 2.0 (without Kobe) with a decent supporting cast.
Phoenix has a good core. With CP3, a guy who had been to finals before, has solid experience in the playoffs and is one of the top 5 PGs of all time. Durant is Durant, who won it all, knows what is necessary to win it and is one of the best offensive weapons of all time. Booker and Ayton are also very solid offensive options, with Booker being an elite himself.
