On Ufc Ultimate fighters do the coaches really hate each other that much?

Yes they really hate each other. Dana White purposely picks coaches that dislike each other for ratings. Also it builds up a good grudge match for the end of the season where he has the coaches have a superfight. Tito Ortiz and Ken Shamrock, B.J. Penn and Little Evil, and now Matt Serra and Matt Hughs. There is no acting when it comes to their disdain for one another.
