There are a lot of head coaches in the sports world who, in the words of Eminem, "just don't give a f***." Some of them show it by being short with the media (we see you, Bill Belichick!). Others do it by confronting their fellow coaches (hear that, Jim Harbaugh?). But regardless of how they show it, it's clear that there are a lot of coaches out there who do not give any fux when it comes to what other people think about them. And with that in mind, Bleacher Report just put together a list of 20 such coaches over here. Some of these guys are great coaches. But we definitely would not want to get stuck alone in a room with them anytime soon.
