Kinda rude man. I spent a lot of time on this and it’s fun and interesting to me (and apparently others too).
Aside from that, your condescending and dismissive comment misses the point. This is a way to evaluate who exactly is the type of player necessary to take a team all the way. There are plenty of players - Ja, Derozen, Zion, Lavine, Fox, Sabonis, Trey, Ant, Butler, Mitchell - who do not meet the criteria but would still be considered “elite prime” players by a lot of people.
No one wins with fewer than one 1st team all-nba player.
There are far more teams with just one 1st team guy, so that means that the chances of team with two such guys winning is higher in any given year than teams with just one.
