Isn’t the goal of every season to win as much as possible? To compete for a World Series?
Not necessarily.
In a typical 162-game season, sure, clubs should try to build a roster that has a good chance to compete for their division and go deep into the playoffs. That marathon quantity of games allows for the ups and downs of injuries and performance to even out. Talent usually wins.
When the season (and the talent) are compressed, the more random variance enters the equation and the less control a club has over their destiny.
