It all depends on who finishes first honestly, best player on the best team tends to win. And even if based on stats alone Green will have to elevate again if he expects to win it. Pretty crazy but if you compare Green's stats last season to Mosley's this year, Mosley's beating Green in every major statistical category from last season and his team will likely finish with only one less win.
Mosley 20-21
19.7 ppg on 51.3% shooting
6.3 boards
3.4 assists
1.2 steals
Green 19-20
19.7 ppg on 41.6%
