The OIL is made up of three 14-team conferences. Each conference plays a 13-week, balanced schedule. Six teams make the playoffs with the top two seeds receiving a first-round bye. The playoffs take place in weeks 14-16. Each conference champion receives its respective league's traveling trophy and a custom team jersey. The two highest-scoring champions face each other in week 17. The winner receives the Tenequer Memorial Trophy and a custom team mini-helmet.
