If the excuse were that he wasn't familiar with the rubrics and needed more practice, that might be one thing. However, he is saying he didn't like the new translation, which is different. He would never be happy with it, no matter how much time he had. Too bad he couldn't have approached the bishop earlier, such as a few years ago, when they started working on the translation. I don't know that it would have changed anything, but he wouldn't have to wait until the last minute. It's too late now. A priest has to work for his bishop and his parish. This man may be more at home in the Episcopal Church or somewhere like that.
