So what you’re saying is that those start times suck for everyone. You’re making my argument for me. The 1-8 system made the matchups between central and pacific teams far more frequent.
If we fast forward to when Seattle enters the mix, the NHL will have 7 PST teams in SEA, VAN, Vegas, LA, SJ, Ana along with AZ which does not observe daylight savings, thus is on PST during the playoffs.
CAL, EDM, COL are Mountain time.
STL, DAL, NAS, CHI, MIN, WIN are Central time.
If the NHL takes the fact that AZ will be PST during the playoffs, they may opt to swap CAL and EDM to the Central and move COL to the Pacific Division if they are going to maintain a division based playoff system. This allows for the first 2 rounds in the WEST to be played mostly in PST or CST.
Going to a 1-8 system puts it all out of whack. Is it a reward for a Nashville to have to travel to LA during round 1? Or a division winner on the west coast to have to go to Dallas or Minnesota in round 1?
You could justify having the EAST doing a 1-8 format since there is no time zone consideration. But, in the West, you probably want to have it division based. They did use 2-3-2 format back it the 90's, but the higher seeded team didn't like having fewer home games than the lower seed during the series.
