If you're in the same time zones roughly it's harder to space games out without them overlapping. In other words, with East /West you know there's gonna be a 10 or 10:30 eastern time. If most of the games are in the same or similar zone, the only way to get the games in is to schedule them concurrently
I see what you mean. In the worst case scenario where all 1-8 teams are on the West coast, the weekends shouldn't be a problem, but during the week, there's not 2 west coast timeslots after 6pm PST (the earliest you could start a home playoff game imo) that wouldn't overlap yet still air early enough for East Coast viewers.
If they keep divisions, what if the seeding is first done by division winners, then the remaining 8 "wild card" teams are decided purely by record? Then the first round will surely have an equal number of eastern/western home teams. By the second round they should be able to space the games as needed.
Not true 1-16, and I'm sure folks will not like the notion of a division winner with a worse record than a nondivision winner getting home court advantage, but a step in the right direction.
