In 2015, the Sandites won two of their non-district season-openers just to forfeit them due to playing an ineligible transfer student. Their third game was canceled at half time due to lightning after having already been postponed two hours. They were leading Guthrie 18–6 at the time it was called off. Sand Springs registered only two true losses in the regular season, to Bartlesville and Booker T Washington. In the quarterfinals Sand Springs dominated Stillwater, then narrowly upset undefeated #1 Booker T Washington in the semi-finals for their first Championship appearance since 1966. This time, Bixby won the rematch and defended its state title.
