There are 5 really legit contenders this year
Lakers - top 5 player, arguably another top 5 player
Clippers - top 5 player, top 15 player
Nets - top 5 player, arguably another top 5 player, arguably another top 15 player
Sixers - arguably top 5 player, top 20 player, all star level 3rd
Bucks - top 5 player, arguably 2 other top 20 players
You see the theme. You need a top 5 player or at least arguably a top 5 player.
I think just about everyone would agree the top 3 players are Giannis, Lebron, and KD. Most people would have Kawhi at 4. As for the 5th spot, I think you could make reasonable arguments for Embiid, Harden, Davis, Jokic, and Curry. The simple reality is, unless you have 1 of those 9 players (Doncic is rising as well), you don't have much of a chance of actually winning a title.
