There are six forward spots, right? Centers are separate for All-NBA?
Giannis, Kawhi, Lebron and Zion are all locks.
Tatum could make it, though. There's no other forward ahead of him in PPG other than Durant, who has only played 19 games. His competition is Randle (fewer PPG, less of a profile), Davis (23 games played), Butler (lesser stats on an equally mediocre team), Paul George if they list him as a forward, etc. I'd like to see Hayward rewarded, but he doesn't have the counting stats.
So, yeah, I would slot Jayson in as third team. Durant and Davis are both clearly better, but they've played less than half the season.
