I am watching the EURO2012 soccer tournament between Croatia vs. Italy and the referee gave an Italian player a yellow card for a bad play. The viewers instantly got an instant relay of the tackle and clearly it was not a yellow card offense. If we can get the instant replay of the game on a fly then certainly the referee can get that as well. A 4.5 led screen attached to his wrist in the form of a stop watch where he can at a touch off the screen see the same replay as we did allowing him to make a correct call. I am sure this technology is coming to allow referees to make correct calls not only for soccer but for all the games that need instant replay.
