Leagues that aren’t using H2H scoring all have games and innings caps. You can find what those caps are and your team’s progress towards them by scrolling to the bottom of your lineups page or visiting your standings page.
They are also documented on the forums for the short season specifically.
Game and innings caps exist so that one team does not win the league by having more games played than anyone else. It keeps a level playing field that is aligned with how many games there are in the MLB season.
There are historical reasons for why there are 2 C slots even though it is a 1 C league. This is also called out in the rules under I. f. x.
There’s a lot to track there but hopefully this clarifies the situation. Every team is held to game caps, so I am not sure how any one team could be ‘hosed’ by this, so hopefully this clarifies that.
