I'll go ahead and argue now for 24 and for much the same reason I have historically.

1. It's a significant amount of content under one roof. I know the networks have undue influence, but I think single leagues going larger helps mitigate that simply due to the market share. I don't even think it's a matter of getting the biggest brands you can get. Add members that are relevant in their market and it makes a difference.

2. It tends to generate less travel overall even if you expand outside your region. Basically, it distributes distance over a larger number so most schools don't make long trips as often.

3. More unique match-ups are created and that can keep TV inventory fresh. You need the big brand vs brand games, yes. You also need the consistent rivalry games, sure. But people like watching games they don't get to see all the time as well. That's one reason bowl games and early season non-conference match-ups tend to get good ratings.
