Beating Oklahoma under Dabo Swinney has become the norm at Clemson. However, there was a time when no team from the ACC could take down the Sooners.
Prior to 1988, ACC teams were 0-16 against Oklahoma on the football field, including an 0-2 mark from the Tigers. The Sooners beat the Tigers 31-14 in Norman, Oklahoma in 1963, and then 52-3 in Norman in 1972.
However, things change. Clemson had become a national power in the late 1970s and in 1981 won its first national championship. The Sooners were still one of the powers in college football and won the national title in 1985.
