Further expanding the postseason in 1994* with three divisions and a wild card created a lottery in many ways. The end season hot team making a run, sometimes winning it all. This team or that team making the clutch hit or defensive gem or pitching performance at the most opportune time in a series. I personally have no issue with Atlanta winning the whole thing this year, unlike say Florida's rental team in 1997 (granted, feck Jose Mesa) or when the 2006 Cardinals rode a postseason wave after winning 83-fecking-games (only the Mets surpassed 90 wins in the NL that year).
The only way I can see a true reward for clubs that dominate the regular season is through a one-table, balanced schedule system but that will never happen in US sports. For MLB I am unsure how a balanced schedule would look. There could be no inter-league play, which I would be ok with. If inter-league play remains then all 30 clubs must play against each. Then how does the scheduling work.
If two clubs were contracted one could create an AL and NL table were 14 clubs play 156 games, i.e. each club plays the other 13 clubs 12 times, 6 home and 6 away, no inter-league play. The top two in each league qualify for the postseason.
Without contraction, perhaps one league has 16 clubs and the other has 14, this would yield 156-game seasons for each league. However, the 16-team league would split along this line - play 7 clubs 12 times, the remaining 8 clubs 9 times - which creates an imbalance. Also, this scenario could perhaps see the addition of two new clubs to increase the 14-team league.
*I know it was cancelled that first season.
