Butler numbers look great and he is a great defender but he missed 35% of games so far. And his 3pt% is 20%.
Durant missed too many games too.
If Embiid is out 3weeks that would be like 15+games that he will miss from beginning of the season and with his history is likely to miss few more by the end of season.
Giannis is playing good but i doubt he gets 3 in a row. Bucks are also not that dominant this year.
Lebron is having a good season but in my opinion his only advantage is being 36. But since when MVP award became a lifetime award

Several guys are having better seasons
Harden is playing amazing but the big part of that is Durant being out. When he gets back his numbers will drop.
Doncic- if Mavs get enough wins to be in top4 in west i think he has a good chance.
Jokic like someone said by advanced numbers is top10 in history in several stats. He also has least help out of all the guys mentioned above. His biggest issue is Denver might not be placed high enough. If they manage to get in front of Lakers or Clippers i think he gets it.
There is also Paul, Lillard, Curry, Gobert.... Definitely a great year by a lot of guys.
