If our leadership has made up their mind to change coaches but keeps him in place for another year anyway, then they are piss poor leaders and I hope they aren't around the University very long.
You don't make long-term decisions based on short term problems. That is some lifetime middle management decision making right there. Awful plan.
If you decide the person you have in the job will never be good enough, you remove them and hire someone who you believe will be. If you hire the right person, that short term problem will take care of itself.
