They saw an opportunity with Harbaugh on timing and they acted immediately by canning Hoke. Did they wait for more data points in year 5 like we did with Weis? No. Did they fire Hoke only because they had a better option waiting in the wings (like many ND fans want to do with Kelly)? No, they had seen enough of Hoke to draw a conclusion (as most sensible football people have with Kelly). And while they rolled the dice by firing Hoke, they had a plan. They've been patient but deliberate. They also have had the balls not to screw around with insulting contract offers like ND is prone to do.
