Rule 4, Section 3, Article 3:
A live ball is in the front court or back court of the team in control as follows:
a. A ball that is in contact with a player or with the playing court shall be in the back court when either the ball or the player (either player when the ball is touching more than one) is touching the back court. It shall be in the front court when neither the ball nor the player is touching the back court.
c. During a dribble from back court to front court, the ball shall be in the front court when both feet of the dribbler and the ball touch the playing court entirely in the front court.
Regardless of where the throw-in spot is located, the throw-in team may cause the ball to go into the back court.
Article 8 (THIS IS THE BIG ONE):
After a jump ball or during a throw-in, the player in his/her front court, who makes the initial touch on the ball while both feet are off the playing court, may be the first to secure control of the ball and land with one or both feet in the back court. It makes no difference if the first foot down was in the front court or back court.
Syracuse should not have lost possession. This was a clear mistake by the referees. Of course, nothing can be done now, but it needs to be pointed out.
