Saints misjudging opponents in season openers

Sometimes I think NO highly overestimate their opponents in season openers, but ALWAYS come to this conclusion - It's not the lack of what the Saints have, its been the preparation of opponents TOO BEAT New Orleans! Who would have ever though that Oakland a few years back, then Minnesota then Tampa Bay even won. Beating New Orleans in the very first game after all the off season preparation to be greater than past.
