Beyond 16 requires either divisionless play or an NCAA rule challenge that would permit conference semi-final games.

Pods don't work.

In theory one could go to 21 in basketball, single round robin 20 games. But to honest I prefer double round robin, so 11 would be my Basketball ideal.

You can make larger numbers work. Even numbers for Basketball mean you designate a rival you always play home and away. With 14 you'd play 6 of the other 12 twice, 6 once, hosting each 3 times in four years. For 16 it takes 7 years to host each 4 times (your rivals always). At 18 you might as well forget rotation, just designate 3 rivals, host the other 14 every other year -- you are basically like the old Big East.

For odd numbers above 11, you need an even number of "rivals" or none at all. If none then for 13, if you play 18 games, you host every school 2 times every 3 years, at 20 games you host every school 5 time every 6 years. If you declare two rivals and 20 games, then you host the other 10 schools 4 times every 5 years. At 15 you host the 12 non-rivals 2 times every 3 years. At 17 or 19 it's a bit complicated - you are probably best off having 2nd games only for rivalries or TV match ups (NET boosters).

For Football it's not great above 14. If you play 8 games it would take 7 years to host every school in the other division. At 16 it would take 16 years with only 8 games. 16 IMO dictates 9 games, as you are not a conference if you only host some schools less than once a decade. In fact 10 games might make sense at 16.

Football at 15 maybe better, with no Division. You could probably designate 2 rivals you always play, and in an 8 game schedule play 6 of the other 12, so that you host everyone every 4 years. At 9 games it's funky.

Football just wont work above 16. You are getting tow a point where Divisions are de facto conferences. If you have 18, you are playing 8 Division games, and only 1 of the other 9 schools with 9 games, which might as well count as OOC.

Scheduling basically says 16 is as big as you can go without de facto turning Divisions into conferences, or turning basketball into an every other year hosting affair, ending rivalries.
