Notre Dame watched a video of great boxing knockouts knowing their game against Louisville would probably be bruising. It turned out to be the longest game in Big East regular-season history. "I talked about it being a 15-rounder and taking punches and being put on the mat," coach Mike Brey said. "At the fourth or fifth timeout I said, 'Has there ever been a 20-rounder?' " If so, it couldn't have been any more thrilling than the No. 25 Fighting Irish's five-overtime victory over the 11th-ranked Cardinals on Saturday night, a 104-101 decision in which the two teams traded great plays and missed shots.
