Offensive coordinator Hue Jackson likes the way the Raiders move the ball with Bruce Gradkowski at quarterback, but is concerned about how he takes on defenders. ?I?ve told this young man, ?What are you doing? Get yourself on the ground,? ??He?s not a running back, he plays quarterback. He has to understand that he?s the quarterback of our football team, and we don?t want him taking those unnecessary chances of trying to demonstrate how tough you are. We know you?re tough. ?I want him to get down and make sure he?s able to live for the next play.?? Jackson also thinks Gradkowski is partially responsible for the four sacks the Texans had. ?I know on the offensive line, they would tell you that there?s some things they wish they could have done better,?? Jackson said. ?But I also know, and our quarterback understands, that we have to get this ball out of his hands. We had three sacks that he was directly involved in. That ball needs to come out, We?ve got to make great decisions with the ball.?
