They got MPJ - if he is healthy, he could be an upgrade.
Why will Doncic not play?
They are getting back their starting PG and added a nice lottery pick. They will be much better.
The Suns sure have. They got the #1 pick and Ariza. They will be better.
MPJ is not going to be the Nuggets answer this season. He is struggling with a bad back, will probably be injury prone, and still has to prove he can adapt to the NBA level. I'm not sold Denver has a meal ticket to the playoffs. Chandlers absent will hurt. They are listing Authur as a SF, they don't have a great PG (Harris is good, but he is overpaid) The Nuggets have Jokic and Millsap and youth. There will be struggles.
There has been talk that Doncic will stay overseas. He has 2 years left on his contract over there. He may not come over. Even if he does. With him and Deandre, the Mavs will be better, but still will probably miss the playoffs.
The Grizzlies will get back Conley sure, and they picked up Anderson and picked up Jaren Jackson. Evans meanwhile walked away in free agency. There is definitely some progress there. If Conley can stay healthy, and if Jaren Jackson can translate to the NBA, then they will make a run at the playoffs. Anderson will definately help them. They got a little better. The west is going to be a beast. Is that little better going to be good enough? I don't know.
The suns...Ariza really? Ariza doesn't make them much better. They got Ayton, Bridges, and Okobo. They have talented youth and quite a few questionable players. In a couple of years they could be quite good. This year will be rookies integrating, young players like Bender and Chriss trying to prove they aren't busts, Booker holding things together, and Ariza wishing he were still in Houston.
