The 1917 college football season featured an unbeaten (9-0-0) Georgia Tech Yellow Jackets team winning the Southern Conference, and a 10-0-0 Pittsburgh Panthers team dominating the Eastern Independents. Things were great for fans of those two schools.
Then came World War I, followed by the Spanish Flu pandemic. Many schools decided to cancel their 1918 football seasons, but those two teams - now in the ACC, along with the Syracuse Orange[men], Boston College Eagles, Virginia Tech Hokies [aka Gobblers], North Carolina State Wolfpack, Wake Forest Demon Deacons, Clemson Tigers, and of course, the Notre Dame Fighting Irish - decided to play through it.
