Its a fine line and I don't know where the line is.
I'm not down on Desormeaux "long term" (two more years) but to your point, that is because of the path taken years ago with WBB.
Namely, allow a coach who was not producing to stay forever (figure of speech)
They've done it several times with WBB and now its to the point they have to give games away. I feel bad for Brodhead taking over a program like that.
