It's the football gods, Herv. The Texans messed with fate by trying to gloss themselves. Everything was going great until they started trying to make up their own nickname. They were overcoming adversity. Rising from the 9 years of mediocre muck to be something greater than anything of the past decade. They had a coach that could outcoach the head coach. They had a lucky 13 talisman that was doing things unheard of for this team.
Then they decided to have a parade.
You don't gloss yourself as a unit/team before you earn it. Nicknames are bestowed upon you because you achieved a status of greatness, usually after winning a meaningful championship.
They gave the football gods a middle finger and those gods turned it around and shoved it up the team's collective butts.
Hey, is all this voodoo and witchcraft real? Probably not. But it certainly makes me feel better than the reality of the situation. Losing to a 1 win Colts was a punch to the gut.
