I don’t think you are getting the idea behind Crowe’s lecture. He is saying the same thing as Safehands, basically. He is against the use of Hawkeye to predict the path of the ball once the umpire has made his decision, so he is certainly not seeking to make them redundant. Also, he is saying that all countries should make the same use of Hawkeye. Refer to this remark: “Overall, in my view, umpires still have the best view; they see and hear everything in real time and they see everything as three-dimensional. The best umpires have an enhanced sense of sight, [and] sound, and an instinctive feel for the game. The best umpires have the nerve, the concentration, the experience and knowledge and - especially if they have been former players - they have the instinctive ability to make the right call under the severest of pressures.”
