Watch as the Center correctly rules this play a foul on the player in black as he pulls the player in white to the floor while attempting to gain control of a rebound. There could be a discussion for an intentional foul on this play, but the contact is not excessive and looks worse than it was since both players' momentum is going backwards and it appears that their feet get tangled. The important thing to take away from this play is what the crew does after the foul occurs. Your awareness should go up when you have a foul like this which might provoke a response from the player or team who was fouled. Don't vacate the area until everybody is up clean. The Lead does a good job of closing on this play as he recognizes that there might be a problem. The crew also displays excellent teamwork by communicating with each other and making the correct call. 

In this play, the Lead is in a great position to see space between the defender and the player with the ball on a drive towards the basket. He could have done a better job of not allowing his shoulders to become perpendicular to the endline, but is correct in ruling this as a foul by the Gonzaga defender as he never obtains legal guarding position before contact occurs. He also does a great job of awarding two free throws to the Dematha player as he had begun his normal throwing motion before the contact occured. Review Rule 4-11 and be sure to include it in your pregame.

The camera does not do a great job staying with the shooter, but the official does.  Watch as the defender walks under the shooter before he has returned to the floor.

Should this be a shooting foul or spot on the endline?

The defender goes through airborne shooter.
