A post player runs toward the basket for a pass from the guard. A defender steps into position and plants both feet right in the post player's path, a few steps away. The post player catches the ball and then immediately slams into the defender. What call should the lead official make?

a. incindental contact; no foul
b. charging foul
c. blocking foul
d. intentional blocking foul charging foul

How would you answer this question?

If this is for Federation rules, the correct answer is not listed.

It should read (e) a player control foul. The contact is certainly not incidental. The foul is not charging because charging is when a player does not have the ball. It is not blocking because the defender legally obtained that spot on the floor. It is not whatever d is because d is quagmosh.
