I think it's about balance. I loathe the hubris as I always feel it's going to come back and bite us. There's a reason why we're one of the Super Bowl favourites but we have to take a game at a time and not be disrepectful to any of our opponents. Starting to sneer or dismiss them is just asking for trouble.
To put in blunty, Miami have the talent to beat us if we're not at our best. But if they do beat us, it won't be down to Tua. It'll probably be a mix of Hill, Waddle and us beating ourselves.
ETA - but we have to focus on the Titans first.
