According to a number of articles, the idea of pods, where four teams play a round robin, is not the favored solution. Three permanent rivalries for each team is the preferred solution as it provides better TV inventory, and maintains more of the important historical and geographical rivalries. Having each team play three permanent rivals, and then expanding to nine games means that you play every team at least every other year. Again, this provides for superior TV inventory, and a better fan experience. Sankey has spoken out in favor of this at some level.
