How to Make the NBA Playoffs more interesting

The NBA has to do something about their playoff system. The series have been competitive but the games have been blow outs for the most part. How do we get more competitive games and have the two clearly best teams challenged? Maybe reseeding the playoffs to 1-16 with the 16 teams with the best record instead of 1-8 from each conference. This year would've looked like this:

1 Warriors

16 Bulls

8 Clippers

9 Wizards

5 Cavaliers

12 Grizzlies

4 Celtics

13 Bucks

6 Jazz

11 Hawks

3 Rockets

14 Pacers

7 Raptors

10 Thunder

2 Spurs

15 Blazers

So maybe getting the Cavs and Warriors in the Semis isn't that great either. Its not that we aren't going to get the NBA Finals we want to see but upsets are exciting too. Maybe going to pool play with the four best teams hosting a pool. Then the four winners of the pool play seven game series. That would've looked like:

Warriors Pool:

Warriors

Clippers

Grizzlies

Bulls

Spurs Pool:

Spurs

Raptors

Hawks

Blazers

Rockets Pool:

Rockets

Jazz

Thunder

Pacers

Celtics Pool:

Celtics

Cavs

Wizards

Bucks

These are just ideas to possibly make the playoffs more interesting.
