PREVENTDEFENSE
Prevent defense
The prevent defense is a defensive alignment in American football that seeks to prevent the offense from completing a long pass or scoring a touchdown in a single play. The alignment uses seven or more defensive backs, preferring fast players over large players. They back up so far that they concede short-yardage plays, but try to ensure that no receiver will be uncovered downfield or can get behind them.The above text is a snippet from Wikipedia: Prevent defense
