I know facts about his job performance and those are all the facts neccessary

I really don't think you do. There are only four people who would know---Wolfzorn, the AD, the Principal, and the Super. Unless you can post that you have information from one of those four or someone close to them, you don't know. Since I'm sure you "know" and will have an answer, tell us what they told him when they let him go, too.

I think from what I am gathering from Btownguy is that he was told that he wasnt coming back as a teacher but could as the coach. He got ticked, hurt feelings, whatever and he missed some days. The administration didnt like this and said forget about the coaching job. Is this not true?

I don't think the teaching job got him tick off as much as the coaching job and how it was handled. As sticky mitts referred to, there's more to it than that.
