Here is the exception that allows the ball to go into the backcourt under NCAA rules:

Rule 7, Section 6

Art. 8. Regardless of where the throw-in spot is located, the throw-in team may cause the ball to go into the back court.
Art. 9. After the throw-in ends, an inbounds player in the front court who is not in control of the ball may cause the ball to go into the back court.
