Im not a huge NBA fan but I enjoy the playoffs. They actually try every game in the playoffs. They should dump some games from the regular season but thats an debate for another thread, this here is about the playoffs.
Use the NFL model. 6 teams from each conference. 4 division winners + 2 wildcards.
1st round wildcard. 3 game series (top 2 teams from each conference get byes)
3 game series increases the likelyhood of an upset, top teams are rewarded by avoiding the short series.
2nd round 5 game series.
Conference Finals 7 games
NBA Finals 7 games.
Im sure theres some financial reason for having a 900 game postseason that ends on the 4th of July, but I think this model would be the best for fans.
