Throw-In/Inadvertent Whistle

[MOofficial]

Situation

NCAAM

Team A has the ball under their basket for a throw in with pressure by the defense on the thrower. The offensive player throws the ball in which is tipped by the defensive player, the ball hits the ground and the official thinking that the ball had been hit oob blows his whistle, only to realize that the ball was still actually in play.

Official says that an inadvertent whistle goes pack to POI and that the POI was the loose ball and that no one had team control. Since he said no one had team control he went to the arrow to determine who would receive the ball.

My thinking is that a team does have team control on a throw-in and a simple pass deflection does not negate team control. Therefor, when the ball was tipped by the defense and on the floor that does not negate the team control. So when the inadvertent whistle came and we go to POI, team A still had control of the ball, so team A would get the ball back.

Let me know if this is correct/incorrect and a rule reference or case book play to go along with this.

Thanks
