Oakland Coach Lane Kiffin began calling JaMarcus Russell 'Big Boy' last season. ?It was funny to me,? Russell said Thursday. ?But most of my family, like my grandmother, she kind of took it hard. But at the same time I think it?s all fun and jokes, just a reason to get myself better and just keep myself in shape.? Russell said that he weighed 269 pounds and looked thinner than he did a year ago as the Raiders began their off-season workouts and that he wanted to lost five or six more pounds before the season. ?I think it shows his commitment to the team and to the players; they see that,? Lane Kiffin said. ?They notice his body being different. He?s got great energy about himself, and he looks really good. He?s moving around great and making plays on the run. I know it just creates a good feeling around the locker room as well.?
