The seas are roiling the Louisville program. After postponement of five of the last six games, the latest just hours before tip-off, the team and medical authorities are at odds on which players should be cleared to play. All but one made the trip, but it’s unclear if all will be active. Regardless, the disruption could leave the Cardinals ill-prepared. The Tar Heels’ 13-7 straight-up record, so-so by UNC standards, is misleading. They have played only seven home games.
