I think the below video should be a lesson to all NBA players who attempt to screen out New York Knicks center Tyson Chandler.
During the Knicks-Bulls Sunday affair, Chicago Bulls forward Mike Dunleavy Jr. was attempting to set a screen against the Knicks big man.
Watch as Tyson decides to have to regard for that screen by sending Dunleavy flying backwards onto his behind:
