The block is called a cut block, not a chop block. Cut is legal. Chop is not. Many programs use the cut besides Navy and Georgia Tech, including USC, Northwestern, and Stanford. It is particularly used in the short passing game. There is no rush for a rule change on the cut because the coaches don't want a rule change. They bitch about the way Navy uses the block but say nothing about other non option offenses that use the same technique. Paul Johnson has challenged a study be made on defensive injuries against the cut vs injuries against teams that don't use the cut. The challenge was never accepted for obvious reasons. So, what is the real reason for the hatred towards the Navy football program? Naval officers? Taking orders? Out of 80k at the stadium on a Navy game day, you would be hard pressed to find one fan who hates the Naval Academy.
