Yes, I actually do know about the program. My location has nothing to do with it.
The thing about coaching is that wins are expected. There comes a point in the program where being competitive isn't going to cut it. I'd say five years is a good scale on that. Heck, most coaches get three years anymore. That is part of coaching. He will get another job and put the same effort into it, no doubt about it.
They went from 10 wins last season to 5 this season. That, despite any competitive "improvements", is a drop in wins. 5-25 in conference play doesn't bode well either.
Again, there is nothing shady about being let go after 5 seasons with a record of 30-80. There is no argument to state otherwise.
