Why would you expand playoffs when clearly best 8 teams in east are getting in while the other 8 are trash? Why reward bad teams?
Because the TV networks won't be satisfied until the regular seasons don't exist anymore; they want that sweet, sweet playoff money, so the goal will be to expand them until we basically start each season with best of 3 rounds or something.
We're seeing baseball do it this year: they're expanding to a 12-team playoff, what the NFL had until last year, but MLB is still a league with only 30 teams, so they're inching closer and closer to half the clubs qualifying and likely getting into a NBA situation where there'll be a bunch of seasons with sub-.500 teams qualifying. For a sport where the 162 game regular season is the main draw, it's ludicrous, and all but kills the entire concept of a "pennant drive" late in the season. Look at the NBA doing its new play-in round, which is a bit less egregious but still makes it so 20-of-30 teams get some kind of postseason play, even a bunch of them outright suck. And again, the NFL even just added a third wild card to each conference, a spot for some 6-8 win club to stink up the joint against a top seed.
I can at least get the argument for expanding them in the NHL a little bit more: historically the Stanley Cup playoffs have always included a higher percentage of the overall teams in the league, including some stretches where essentially everyone made it, the regular season being purely about arranging seeding. If one wants to argue that's more intrinsic to the NHL's identity, and thus the playoffs should be expanded to reflect that, I can at least see where they're coming from.
But the idea that, say, it's a bad thing that the top 8 teams in the East are so good and the bottom 8 teams just...aren't is some kind of major problem the league needs to address? How about the clubs in the bottom 8, I dunno, get
better? Like you said, the Islanders are friggin' 20 points off the playoff pace; on what planet do they deserve a spot?
I guess there's the whole "it makes the end of the season less exciting without playoff races" argument, but like...yeah, that just happens some years. There are years where there's a mad scramble for the last couple of spots, there are years where there's considerably less drama. It happens.
