Last year the 6 All-NBA forwards were James/Leonard/Durant/Green/Aldridge/George
Hayward is for sure having a better year than Aldridge and George, and you could argue over Green too if Hayward can get Utah to a 1st round homecourt advantage while putting up stats.
There are dudes like Giannis who really busted out this year, but he isnt going to be on a playoff team, so he will get votes against him for that. Every player on the All-NBA teams last year where on playoff teams.
So if you hold the same top 4 from last year and cut out George/Aldridge, it's a 3 man race for the last two spots between George/Butler/Hayward and Hayward will likely have the best record and 2nd best raw stats among those 3.
*Edit* Cousins made All-NBA 2nd team last year, only non-playoff person to do so.
