The Notre Dame Fighting Irish, Colorado Buffaloes and South Florida Bulls have vanquished all foes on the football field. But their most formidable opponent — abundant air travel — still looms large on the schedules of these three unbeatens.
The No. 5 Irish, who play at home this weekend against the Pittsburgh Panthers before a bye, still have 5,081 miles left to travel on their schedule. That includes two trips to southern California and an excursion to New York City, in addition to their 114-mile jaunt to Evanston, Ill.
