Shrug, at the risk of sounding overly diplomatic, there's valid reasons for concern (DA, the offensive line, the revamped DL), and hope (the TE room, Williams should be a better RB to pair with AK41, an improved receiving corps in general, weak schedule).
Before the season starts, whether you're an optimist or a pessimist, I'd just hope you'd have the humility to acknowledge you might be wrong because we don't know yet (personally I think a division title is certainly within the realm of reasonable possibility). And while some of the arguments devolve into silliness and pettiness, the forums would be pretty boring if every post was "Yay Saints! Surely this will be a great season!"
