As to the worst three game stretch there is the Oklahoma(2), Penn St (15) and Maryland(18) series in 1974 in which Wake lost 63-0, 55-0, and 47-0 all on the road. As the naming of the then New Dorm was being held for the next million dollar donor, it was named Oklahoma Dorm, Penn St Dorm and Maryland Dorm for a week after each of those drubbings. It should be noted we lost at home to UNC 31-0 and to Virginia 14-0 (in what was considered a moral victory) as bookends. We lost by a combined 210-0 over that five game stretch.
I think we scored 5 rushing and 3 passing TDS that whole year (lost to Bill and Mary and our sole win was the last game of the year in the Baptist Bowl vs. Furman when a seemingly last second catch in the end zone was somehow called incomplete as the ref sprinted to the lockerroom)
