Baseball need its own, unique, system of playoffs. Unlike other sports who have the same players on the field for every game, the better baseball team is often the one who has the most pitching depth. The decision to go to one game "playins" for the wild card team is another gimick that cheapens the game.
Some statistically oriented folks have pointed out that the odds for who wins one game between even two mismatched teams is almost the same as flipping a coin. But, while that is true for a random regular season game, it isn't true in a single playoff game. A one game playoff rewards a team with one really good starter and a great closer over a team with depth in both the rotation and the bullpen.
Almost all the demands by bloggers that the Twins get an "ace" are based on the value of an ace in a playoffs where pitching depth is a lot less important. The emphasis on winning just one playoff game diminishes even further the value of putting together the best team for the regular season.
What they ought to do is restructure the playoffs to give a win to the team with the better record at the start of the series. So the team with the better record would need to win one game in a "three game series", while the other team would need to win two. Of course the teams would actually only play, at most, two of the three games. In a "seven game series", teams would play six games and the team with the better record would need to win only three games, while the other team would need to win 4. That would make the regular season a much bigger factor in who ended up in the World Series.
I would love to see baseball go back to one winner in each league. They could schedule two home and away series with each team in a 13 team league plus one home and away game against each team in the other league. That would be 170 game schedule. It would turn those one game interleague "series" into an annual event for the local fans of that team. Imagine how many Cub fans would show up for its single game each year against the Twins.
Then you would have the next six teams in each league do "three game playins". If the teams had the same record they would play all three games, otherwise the team with the better record would get a win to start and they would actually play only two games. The three winners of the playins and the division winner would play "seven game" series, but the league champion would get that one game gimme in each series. So teams playing them would have to win 4 of 6 games instead of 4 of 7. In short, you make getting to the World Series a long shot for anyone other than the league champions. Which is the way it should be.
Of course, no one is going to adopt that convoluted system. It doesn't conform to how football, basketball and hockey do their playoffs. And emulating those other sports seems to be what baseball is after under Selig. Unfortunately, part of baseball's appeal is that it is unique. It has already been surpassed by football as the national sport. As it becomes increasingly just another sport, its place in American life is going to be further diminished.
