These are the kind of stats people threw around a decade ago. Since then, most analysts have recognized that advanced stats can help avoid some clear situations where these basic statistics get conflated with other factors.

Total assists per game don't account for usage rate or minutes played. If Jordan played all 48 every game and had the ball in his hands 80% of the time, of course he'd end up with a ton of assists, simply because every shot (besides the ones he makes) is most likely to have come after a pass directly from him.

Championships are a very overrated way to rate any player. Tremendous luck goes into winning any championship. Less impactful players can win rings by taking a lesser salary and "ring hunting" with contenders (as you already point out). Championships can be a factor in determining a player's greatness, but let's not make them the sole determinant.

There are factors that work in favor of your argument as well. The pace of the game has increased, so that accounts for a degree of statistical inflation alone (which again advanced stats help to account for). Not sure how these impact things, but hree pointers have become a much bigger part of the game, defensive hand checking is outlawed, and zone defense has been legalized.

This is hacker news, home of the nerds. If we're going to talk stats in sports, let's do it right!
