So the official announcement was 17 new walk-ons, all from Nebraska. @Sean_Callahan has reported 21 new walk-on commitments. What's going on with the other 4? I assume 1 of those, Lane McCullum, is not counted since he's transferring from Air Force. What about Corbin Frederick, Cam Jones' buddy from Texas? Since the 17 announced are all from Nebraska, he apparently didn't sign?
