Currently Major League Baseball has 8 teams of 30 reach the playoffs. New one-game wild card playoffs discussed today for the 2013 season would push that to 10 teams.
At first I thought 30 percent of teams reaching the post season was too high a ratio. Then I read this tonight:
In the NFL, 12 of 32 teams make the playoffs. In the NBA and NHL, 16 of 30 teams advance.
Huh.
