Eh, more slogging big men with a couple of post moves isn’t going to save the NBA.You've defined the problem.
The season is just too long and the playoffs are way too long as well. No need to start before Halloween and finish right before July 4th. There is also no need for the first round to be a 7 game series.
Scarcity dives interest, IMO. College Football is going to be teetering on that line as well as everyone could see how little interest there was towards the end of the playoff vs the beginning of it despite having bigger and better games.
