It could have been a Colorado fan trying to do all he could to help the buffs win and put a bad light on our fan base.
Oh get over yourself. I've heard CU fans accused of some preposterous things in my day, but this is WAY over the top...
Football in Colorado doesn't have that level of fanaticism attached to it, nor will it ever. If you were gearing up to play Oklahoma or LSU, I could see your point being somewhat valid, but that's not something a CU fan would do.
Bad CU fans are known to drink, swear, and occasionally throw things, but they don't threaten the lives of opposing teams' coaches in an attempt to circuitously give Colorado some sort of convoluted advantage in a game that's taking place a month after they make their phone call.
