As this chart shows, many of the teams in the American have a long history of playing each other. Whether you call them rivalries or not. Of course Houston's main rival is Rice, SMU's main rival is TCU, Tulsa's main rival is Oklahoma State, Memphis's main rival is Ole Miss, Tulane's main rival is LSU, Navy's main rival is Army, etc. But new and important ones could develop.
