The two soccer players responding to the former QB rushing for over 100 yards in 1972 by saying they rushed for 100 yards an hour ago is a false equivalency. The opposing team actively tries to prevent you from gaining yardage in football. Running 100 yards in a soccer match is a fairly pedestrian achievement - one would reasonably expect a soccer player to run many times that distance in a single half alone.
At 18:50 Vivian is watching a YouTube video but the play bar never moves and there's no times listed.
