HOUSTON -- To say that the Texans defense of the last three years was vanilla is an insult to ice cream. Last year, a Football Outsiders game charter marked down "4" before just about every defensive snap, knowing it was very likely the Texans were only rushing four defensive linemen, and that he would have to erase only a couple of marks every quarter.This year the theme of the defense is "aggressive." Texan fans have heard that before, but maybe this is the year it may actually happen. Watching in training camp, the line as a group looks to be penetrating upfield faster, and when they do blitz, the blitzes look less predictable. How games will be called remains to be seen, though first-time defensive coordinator Frank Bush said Tuesday that Gary Kubiak is going to give him a lot of freedom on that side of the ball.
