And here's another argument for a 24-team league: more free credits per team in the league. According to SOM:
For 24-team leagues:
- the 4 Division Winners: each receive 1 free credit (awarded at the end of the regular season)
- the loser of the Finals: receives 1 more free credit
- the winner of the Finals: receives 2 more free credits
So the owners in a 24 team league receive a total of 7 credits. That's 3.5 credits per 12 teams, while a 12 team league wins just 3 total. And you actually get a guaranteed credit for winning your division, instead of bupkis, even if you don't make the finals.
