I agree that playoff hockey, and basketball, are the best the sport has to offer. The argument I have always had is the length of the regular season in comparison to the playoffs. Why play 80+ games (or in baseball, 160+ games!) only to have the title decided by a playoff.
As for Bundesliga clubs getting a bye in the first round, that can fuck right off. If anything, I think Buli clubs should have to play away against any lower league opponent, unless the opponent agrees otherwise.
