I'm sorry to pick on you again but I don't follow your logic.Nobody other than Moyes was sacked after their first season. Interesting logic though.
They were all sacked after their first season, Moyes was sacked during his first season. The distinction is somewhat important because they also all had good first seasons and they were all sacked based on their latest performances which would be the case for ETH if he was sacked in spite of a good first season.
