Taking a stab at a Texans song & defense name...

[Playoffs]

All caught up in Texans fever, I'm jumping the TexanFan shark!

Play this SRV YouTube video in the background to see how the words fit:

It's a bit repetitive, but...

The house is a rockin', don't bother knockin'
Yeah the house is a rockin', don't bother knockin'
If the house is a rockin', don't bother coming in

Houston Texans got a new attitude
Come in our house, well, you(you're) gonna lose
We will Rock and Roll you, knock you outta your shoes
We say NEXT MAN UP!* and send you home a singing the blues

The house is a rockin', don't bother knockin'
Well the house is a rockin', don't bother knockin'
If the house is a rockin', don't bother coming in

**skip solos & second chorus**

Houston Texans got a new attitude
Come in our house, well, you(you're) gonna lose
We will Rock and Roll you, knock you outta your shoes
We say NEXT MAN UP!* and send you home a singing the blues

Well, the house is a rockin', don't bother knockin'
When house is a rockin', don't bother knockin'
Cause the Houston Texans
Will send you home a singing the blues!

*everyone yells

( I'm not settled with the last line. )

As for naming the defense, I like Rock And Roll!

Flame away!
