Wasn't the illegal fist to the back in the Dylan Alton/James Green match?
EDIT: El Jefe was too fast for me.
ANOTHER EDIT: The announcing is glorious throughout but the illegal fist call is the undisputed highlight. It comes deep in the match around the 11:30 mark.
A THIRD EDIT: I've watched this a dozen times over the years, and it never gets old. The announcers lament Nebraska coming out on the wrong end of some close matches during this dual meet.
"Nebraska had their chances," one of the announces says. "A couple of points go their way, they could have won it." He mentions the Ed Ruth / Tyler Koehn match in particular. "Tyler Koehn took Ed Ruth to the brink there," he says.
Ed was winning 10-0 and the ref was holding three more back points that would have made it 13-0 when he scored the fall in that nail biter.
