The defending national champs have been gutted by a roster turnover that saw their top three players move on to the NBA. The Cavaliers have returned to the once-familiar problem of lacking enough offense to go along with their smothering defense. Now, they are on the bubble and in need of a signature win Tuesday over Florida State after coming up just short in the first meeting. The Seminoles are coming off a hard-fought home win over Notre Dame, while Virginia rallied for an overtime win at Wake Forest. Look for the Cavaliers to grind out a critical victory.
