Eight days ago, Duke had no point guard and few game-changers among its eight scholarship players.

After Derryck Thornton (No. 17 in ESPN 100) and Brandon Ingram (No. 3) committed, the Blue Devils suddenly have one of the best high school point guards and an elite wing to add to the roster.

Essentially, Duke went from a team that would have little chance of defending its national championship to one of the most talented teams in the country in the span of one week. Mike Krzyzewski has quality pieces all over his roster -- and now he has the depth and personnel to match.
