This is Moos doubling down--trying to calm some waters and rougher waters to come, the schedule will never be as good as it is this year. The extension will hold off some of the pitch forks next year in what looks to be a continuing long arduous rebuilding project. I'm in favor of the move, I'm tired of the revolving door---but this is a major gamble nevertheless.
If Frost doesn't coach us to a bowl game next season, I guarantee many, many more pitchforks than now. A contract or contract extension does not prevent pitchforks.
