‘Multiple is simplifying things. On several occasions, there was no traditional front four. At times, four or five linebackers were in the game with six or seven defensive backs, and none were in a three-point stance. Two defensive linemen were a frequent sight, four a less common one. Sometimes a few of the linebackers would blitz and the others cover. Sometimes all the linebackers would blitz. Other times a DB or two would rush the passer.’
