I don't get the hate from ISU for him at all.
Yeah, most of what I know about him was some minor arguing with Hawk fans on Rivals a few years ago who were dissing the recruiting of his son's. Never a good look for the parental units to go on fan forums but he was proven to be right and the dissing fans wrong.
Edit: Guess he might still be at that some but as an ISU fan it's not something that flips a switch with me.
