I wish you had more faith in sports officials. Speaking for myself as an umpire, after 3500+ softball games under my belt, I have never once had a "make up call." If I miss one call, I'm sure as hell going to make sure I don't miss two. It also makes no sense to do so. I already may have one side mad at me. What's it worth to have both teams mad at me?
Nothing to do with lack of faith and I did not say that you have ever done this. In fact, I have no idea who you are to even make a statement like that.
It has everything to do with experience and nothing to do with faith. Too many times I see a bad call against us or another team and then a short while later a bad call benefitting the team with the previous bad call. Coincidence? Not likely as it happens too often. I have faith that there are a large number of excellent umpires out there. I also am realistic enough to realize that there are a number of umpires out there who are not of the same ethical quality as others.
