I agree, but that's all the more reason to use technology, including replay, to get the calls right. Given what you wrote, there's no reason for the officials to be ashamed when the replay shows that they blew a call, so they should be willing to overturn those calls without losing face. When presented with evidence, it's better to admit having been wrong than to double-down on a mistake. The league needs to make that clear, otherwise the replay process will continue to be, to a certain extent, a joke.
