Interesting.
Coach's parents live in my area. There was an article in today's paper about how they were affected by the show and his portrayal -
They stopped watching the show halfway through the season - said it was too hard to watch him being made a fool out of on national tv.
They were not supportive of him going on the show.
He invited his parents, then his brother to the family part of the show - and he felt bad, "cheated, it was sad" when they turned down the visit - his dad is a professor at the University of Tennessee and had finals during the taping session, and it's hard for his mom to travel because of "bad acid reflux"

(umm, okay). His brother, a teacher in Nashville declined the free trip because of "school work". Coach said "I think he's crazy for not taking a free trip to Brazil, but I respect him for his priorities".
He was fired for not telling the school where he worked he would be gone for two months. He will be in Knoxville in August, for his 20th class reunion, and may look for employment at the University of Tennessee while he's here, but "I don't know if they'd have me after my reputation has been damaged..."
