There's an issue with that, though, because all the teams don't play against the same opponents.
Let's say the Eastern conference is the weakest (like now), then because teams play more games against their own conference, a team from the East could have a better record than a team from the West solely based on strength of schedule.
The solution would be to copy the way soccer leagues work (in Europe at least) with everything perfectly symmetrical.
Make each team play exactly 58 games (that would also make the season shorter, which would be good), 2 games against each team, 1 at home, 1 on the road. Top 16 goes to the playoffs with usual seeding. Better seed = HCA.
Something I'd like to see: the top seeded team CHOSES against which of the remaining team they want to play, and it goes down until 8 teams have chosen. Repeat each round. Top seed = possibility to choose your bracket all the way to the Finals. A good seed would still give a team a lot of control.
