When teaching post defense, every coach in America instructs in the use of the arm bar, that is, using a forearm on the back of a post player as a way to deny the offensive player the ability to back you down.
As long as the defender doesn't extend the forearm and displace the offensive player or use it to control movement, officials will let the defender protect his space.
Except if your name is Ivory Clark and you are doing it in Hec Ed.
Clark's third foul was a perfect demonstration of the correct, and seemingly legal, use of the arm bar. Except he was called for a foul.
Clark was astonished. He also was headed to the bench. And the Cougar defense, as well as the Cougar offense, took a hit.
• The foul totals with 11 minutes: WSU 14, UW 8; the free throws: WSU 5 of 7, UW 14 of 18.
