What's wrong with the way that Major League Baseball (used to) does it? Three division winners, plus a wild card? I'm of the sentiment that the playoffs should be hard enough to get into that just making the playoffs, by themselves, is an accomplishment. As it stands now, 53 percent of the teams in each conference get in the playoffs. That's why coaches can get to the playoffs and still lose their jobs. That's why Hall of Fame talents that don't get their teams into the playoffs get maligned and overlooked.
Of course, it'll never happen: there's simply too much money in it. Personally, I would rather that the regular season were longer, and the playoffs were shorter. But, as with the playoff seeding discussion, I fully expect to stand alone on that issue.
