I doubt that as well. It would be unfair to fire a guy in less than two years or only after two years. Lack of continuity already has hurt this team.
The only way I could see the Pegulas firing McCoach is if we continue to have historic embarrassing losses (or something like that).
Barring something like that, I just don't see it. We already have a bit of a reputation for firing coaches quickly (e.g., Rex, Bylsma).
