I want to know the answer to the following question:
Indoor league teams sometimes play against what type of outdoor league team?
All the background I'm provided with is that "Exhibition games outside of a structured season are relatively common among indoor American football leagues; because teams switch leagues frequently at that level of play, it is not uncommon to see some of the smaller leagues schedule exhibition games against teams that are from another league, about to join the league as a probational franchise, or a semi-pro outdoor team to fill holes in a schedule.". Is that enough to answer the question?
Answer: yes
