Last month in Atlanta, Louisville won the national championship with depth, tenacity, stubborn defense, talent and will. From mid-February on, the Cardinals showcased an unmatched fortitude. Few expected an easy road to the title, but Louisville clearly had the edge in every postseason matchup that threatened to disrupt its mission. And the Cards were the last team standing at the Georgia Dome. Most of the critical characters in that run -- Russ Smith, Luke Hancock and Chane Behanan -- will return. Key reserves Montrezl Harrell and Wayne Blackshear are back, too.
