There is some merit in adding 2 teams to go to 32. You can then either go to eight 4 teams divisions or four 8 team divisions, which should theoretically help with scheduling. So if you went with eight 4 teams divisions, you could play the other conference 2 games each (32 games), the other 3 divisions, 3 games each (36 games), and your division 5 times each (15 games) for an 83 game schedule. That would create better divisional rivalries. Or you could do four 8 team divisions where you still play the other conference 2 games (32 games), you play the other division 3 games (24 games) and you play your division 4 games (28 games) for a total of 84 games. In the first scenario you would just rotate each year the extra home or away game. I know that an odd number may not be ideal, but I think that is a nice even schedule for all teams. It does add some games, but I don't think that is as tough if you theoretically have a bit less travel (if the divisions are properly arranged to minimize it).
