At the Big Ten Championship Game Saturday night we experienced ref cam and the sports world should adopt this innovation immediately. The footage from a GoPro worn on the umpire's hat behind the defensive line was incredible. Also, give the viewer the option to stream an entire game from ref cam. Embrace the future.
And then after ref cam is everywhere take the next step: have the ref wear a microphone so we can hear everything he says to the players like they do in rugby.
