The NBA is pretty awesome, all year long, and what happens is what actually happens, not because the league clearly favors certain franchises.
You're pointing out an issue that has more to do with it being a 5 on 5 sport where one player can have an outsized difference, but if you want to say that has something to do with the way the league is run, ok I guess.
It sure was suspenseful and very surprising watching the Patriots win it all last year.
