With how things played out on our (NFC) side (*cough*GreenBayLosing*cough*, if Schaub hadn't gotten hurt, I bet Houston woulda won the Super Bowl last year. Their D was disgusting, and their offense is deadly (provided they have a competent QB back there, which Schaub is). It's a new year though, so we'll see.
And SF? Hmm...all I'm gonna say at the moment is, we won 15 games last year with an historically bad D. Our D can't do anything but get better, and if JMike shuts his mouth, and plays to his potential? Barring injuries of course? Well...our offense...hmmm...yeah.
