In theory, I like the idea of placing more emphasis on winning the regular season, even winning the division. It provides a more realistic goal of achievement for teams / fans of teams that don't have a realistic chance of winning a title.
I just don't think US fans are wired like that, though. At least not anymore.
The teams we remember are the ones that go far in the post-season. Great regular season teams that underachieve in the playoffs are uniformly considered disappointments (see: 2007 Mavericks).
Meanwhile mediocre teams that overachieve in the playoffs, whether by playing well or just by luck, are remembered fondly (see: 2007 Warriors).
