I'm 100% in favor of scrapping conferences and divisions and seeding 1-16 based on regular season record.
As for tie breakers, why not just use point differential?
Here's how the playoffs would look if that were the case:
Bracket 1
GSW (1) vs CHI (16)
TOR (4) vs DET (13)
BOS ( 8 ) vs CHA (9)
OKC (5) vs POR (12)
Bracket 2
SAS (2) vs MEM (15)
CLE (3) vs DAL (14)
LAC (6) vs IND (11)
ATL (7) vs MIA (10)
Mostly I just want to see the Finals be Warriors versus Spurs. Easily the two best teams in the league this year.
In real life, I suspect the Finals will be hard-fought, perhaps, but not especially competitive in the end, unless there are injuries in the West.
