Iowa defensive end Broderick Binns hopes strength in numbers can help the Hawkeyes overcome some key losses on the defensive line. With the likes of Adrian Clayborn and Karl Klug gone there will several new faces on the defensive line.  Binns says there will aloso be more depth up front.  Binns feels the added depth will help keep the defense fresh. The Hawks gave up several late touchdowns a year ago enroute to an 8-5 record.  The Big Ten Conference looks a lot different as Binns prepares for his senior season. The addition of Nebraska has introduced divisional play and for the first time the Big Ten will hold a championship game.  The Hawkeyes open the season at home on September third against Tennessee Tech.
