Just to play devil's advocate for a minute: In real life golf replays aren't savable, other than in our memory. Which, like fishing memories, just gets better with the retelling.
And I'm not sure if, in a match, I want to wait for my opponent to watch, label and save a replay. Though, granted, I'm sure it wouldn't be that often. But I do know I would want to save the replay of my 3 inch putt that beat Tibbets 2 and 1.
