If it hasn't come up in anything you've read of mine before, I'm an exclusionary playoff person. I consider the playoffs to be a legitimate attempt to find the best team in the league that given year and it bothers me more that a clearly "not best" team makes it into the playoffs, than it would that a "possibly best" team gets left out. The addition of more teams is terrible for a person like me.
But it'll happen. Forget about them "thinking about it". It WILL happen. It's what the people want. They want a regular season that is just an overly extended method of figuring seeding, followed by the most exciting playoff possible. It's what the league wants. They want as many teams as they can squeeze into the playoffs because it creates more interesting games at the end of the season and simply more games in the post-season (or $$$ for short). That isn't in itself terrible. What makes it terrible is the insistence on treating the winner of said playoff as if they were the best team that year. It's not about that. It's about fun for fans and money for the league. They should get the Fun&Money Trophy.
I'm sure I'm repeating myself, but the real truth is that the perfect playoff system to figure out the best team in the league in a given season will never exist because the perfect playoff system would change from year to year based on the play of teams. This is true for all sports. Some years a 10 team tournament may be reasonable. Other years one team may show itself to be clearly the best during the regular season and there doesn't need to be any playoffs. I could live with a season where there is no playoffs. (Of course as Nats fans, so can you)
10 teams... bah
