Look closely at the Cornhusker poster, there's something missing. Let's see, there's Bob Devaney and Tom Osborne, Frank Solich and Bo Pelini ... Wait, where's Bill Callahan, who was 27-22 in four seasons as coach? That's right, Nebraska has taken a page from the revisionist history playbook by deciding to leave Callahan off the poster. Thanks to Sammy at Double Extra Point and our good buddy Paul.
