Firing Mullin after only two years, when SJU knew he was inexperienced and he was walking into a complete overhaul, after doing a huge introduction ceremony, is a great way to do things wrong.
1. The school will burn bridges to their best player in SJU history, further alienating alumni and fans (haha I get it what fans...).
2. The administration will show that they will not have their coaches back when things get difficlult. What coach would want to come to that.
3. A brand new coaching and recruiting philosophy will have to be implemented again.
4. How much money will the school have after spending money on fire coaches to hire a new coach?
The administration took a chance and made their bed with Mullin, and they have to give him enough time and resources for him to be a successful coach.
Two years, one disgruntled coach leaving, not hiring an experienced X&Os coach,, team playing horribly, Rumblings and grumblings from the media and fans, is enough time for the AD to get involved in personnel decisions.
If this season is a complete debacle some kind of change will be needed, but It should not be firing Mullins unless he wants out.
