Officiating Mechanics: Identifying Goaltending and Proper Rotation

The shot attempt by #55 TCU is blocked by #6 Duke, however the ball first hits the glass before #6 gets his hand on it.  This was a Goaltending call missed by the crew.  The Center and Trail officals have primary responsibility on any Goaltending plays.   Lead can assist if they are in position to get a good look and if no call is made by C or T.  As the drive to the basket starts, Lead rotates into the drive and then stops in the paint instead of finishing the rotation. You can see this causes some confusion for the C.  Lead should have rotated to strong side earlier,  before the drive initiated, putting himself in better position to assist on this play.  The Center starts to "leak" and backs out to the Trail postion instead of staying connected to the play and  being in position to call the goaltending violation.  By rule, since we had no call on the floor, this play can't be challenged by TCU.  After this play, the TCU head coach ends up being assessed a class A unsporting technical foul for arguing the non call.
