Been thinking a lot about playoff formats lately. It's obvious to me that expansion to 32 teams will come eventually, and, with it, another expanded playoff format.
The more that I think about this, the more I'd just rather go to 16 teams. No byes. You have two sixteen-team leagues, and I would do two divisions. Win your division, get a top-2 seed. The next two best records are Wild Cards and are seeded 3 and 4.
Essentially, my preferred format is that seeds 5-8 go to seeds 4-1 and must sweep a 3-game series. Winners play a five-game series in the divisional round, and the standard, 7-game LCS. That rewards your four best teams in each league, allows for meaningful division titles, and still creates drama and excitement. It gets a little dicey when you talk about the 5 and 6 seeds having to win three straight on the road, as there might not be a huge difference between being 5th and 6th, but I think that flaw is outweighed by the fact that you're increasing access and rewarding teams for the long haul, even if they were only just slightly better.
I also think the minor league system of dividing things by halves might have some merits. Perhaps that could be incorporated.
The other option might be to just shorten the regular season to 154 (or 150) and go full-on, 7-game series all the way through a la the NHL and NBA.
A big part of the problem is this paradox that baseball is SO much about the long-haul, but American sports insist on a single, winner-take-all, open-access playoff. That system just doesn't fit our sport that well. Hockey attempts to solve this with the President's trophy, which gives the best regular-season team actual hardware, even if fans don't think it means that much. Still, it's something, and that's fitting given that the NHL is our most international domestic league.
The soccer system of having multiple competitions happening at once during a season (and the NBA and WNBA doing these in-season tournaments) makes a lot of sense to me. It provides multiple ways of defining a successful season. For some teams, maybe it's just staying at the top level or qualifying for a minor European competition. For others, its winning a domestic cup. For others, only league and Champions League titles will suffice. Perhaps us fans have to just make that attitude adjustment because there's no doubt the Brewers have been an incredibly successful franchise over the last decade, despite little in the way of October advancement.
Basically, I think, if baseball isn't going to adopt promotion-relegation or some meaningful, in-season competition or celebrate division titles and other things at a level closer to (NOT equal to) WS appearances and titles, then I'd just as soon open the playoffs up, balance the brackets, and not necessarily "devalue" the regular season, but just mark it off as its own unique thing, separate from October.
