Following Clemson's upset of Virginia Tech this past weekend, Clemson claimed to become the first school in ACC history to defeat three straight ranked opponents.
Clemson's sports information department recently issued a clarification:
Further research has uncovered an instance when the University of Maryland defeated three straight Top 25 opponents who were ranked in at least one of the two major polls. In 1984, Maryland defeated Miami (No. 6 in AP, No. 6 in UPI), Clemson (No. 20 in AP, unranked in UPI) and Virginia (ranked No. 17 in UPI, unranked in AP) on consecutive weekends, Nov. 10-24. Virginia was not ranked in the AP poll entering that last game. The ACC media guide only lists games against AP ranked teams and that is how this was missed.
Regardless, it's still impressive. Clemson is the first ACC school to defeat three consecutive opponents ranked in the Top 25 of both polls
