I can only assume you're also not a fan of college basketball. Umm March Madness lasts 1 month and no where near half the teams make the tournament. It still takes a long-ass time and there's still an absurd amount of teams competing. I have no idea why one would expect that the time span for playoffs must occur within a certain amount of time. Why is one month OK, but over one month is not? Yeah, over half the teams in the NBA make the playoffs, but how is that so much worse than wading through 65 teams in a tournament, which is soon going to be expanded to nearly 100? Because one month is around what most playoff systems last. Two months is way too long. 2 months is double 1 month and thus a much longer amount of time. You seem to believe there isn't much difference between 1 month and 2 months. Also playing a factor, albeit small, is the NBA playoffs used to be shorter but they somewhat recently made every series a 7 game series.
