Their rankings had the Texans #1 overall last year, too.
I think the CHFF guys are ahead of their peers. I'm convinced the Texans would've been playing for the Lombardi Trophy last year had Schaub not been injured.
The Texans imo are the most balanced, complete team in the NFL. This team has a solid defense that gets pressure on the quarterback and forces turnovers with an offense that can beat you on the ground or through the air and does it with efficient, time-consuming drives.
Someone pass the party punch!
