From the SFgate:
-- There is no gentle way of saying this, so we'll let the numbers do the talking.
The first four games of the season, the Raiders blitzed an average of 8.5 times a game. Since the death of owner Al Davis on Oct. 8, the Raiders have blitzed more than three times as much - an average of 28.5 times the last two games.
Davis preferred letting his four defensive linemen get pressure on the quarterback, and if a defensive coordinator called a blitz and it didn't work, he was sure to get a late night phone call from Davis.
