I'd say this is a good list - the main reason MJ doesn't top the list is "lack of longevity" including taking nearly 2 full seasons off in his prime.
The way to make this list better is to apply a timeline/difficulty adjustment of some kind. I propose a deduction for each number of years born prior to 1990. (This means Giannis and Jokic get a bit of a boost.) The key issue there is how much of a timeline adjustment to apply. For the time being I'll settle on 1 "point" deducted for every 20 years before 1990 a player was born. For Russell it means a 2.8 point deduction.

AD - 1.395
Kawhi - 1.365

The rest are negative-territory losers and/or the timeline adjustment makes things weirder among those with lesser POY shares
(Given that weirdness the better adjustment might be some percentage of the shares based on birth year.)
