Defensive tackle Tommy Kelly believes that the Raiders defense isn’t the same one that finished 2011. The Oakland defense was 29th in the NFL in yards allowed and 31st in giving up touchdowns. New Head Coach Dennis Allen is installing a new system and Kelly likes what he has seen so far. “To me, the biggest change is probably Dennis Allen and defensive coordinator Jason Tarver. It is just attention to details, the little things. DA harps on that all day long. It helps because you see the mental errors on the field, on the practice field and even in the game, we’re down. The technique, we can fix that. If we cut down on the mental errors and the penalties, people are going to have a hard time dealing with us.” “This is the first time in nine years that we have looked that good tackling in the first game of the preseason,” Kelly said. “So whatever they are doing it must be working.”
