I hardly think scoring champ should ve the one with most points in general than most ppg. Its not Tatums fault for eg that he played more games than Embid. As in all time leading scorers we look at most points global, not most ppg. Thats the top scorer.
It should be PPG over best X (let’s say 70) games. This means that people that are competing for the scoring record can afford to play more games and have bad games without ruining their averages.
