“This is an example of illegal contact in the post. The defensive post player, CJ McCollum, reaches out and illegally grabs and pulls the jersey of the offensive player, Rudy Gay, as Gay looks to receive an entry pass. This illegal shirt grab impedes his opponent’s progress, and it is a defensive foul. A defensive player may not dislodge or re-route an offensive player, nor may he impede an offensive player’s progress.”
