Here’s what I don’t get re Saints ranking predictions

So most national punditry, majority of Saints fans and even Nick and Tripp, et al have the Saints doing no better than they did last year and a good chunk saying they’ll do significantly worse
And I guess the question is ‘based on what’?
Most all have concluded (rightly, imo) that bad Oline play AND bad play calling/personnel usage were the reason we were AVERAGE

Obviously losing Ram is significant BUT he played on one leg last year and we ‘replaced’ him with a top draft choice (yes he’ll need some seasoning)
I feel Oline play is probably going to be same level as last year with maybe a 25% chance of getting better
BUT almost certainly O play calling and personnel usage gets SIGNIFICANTLY better
And with slight upgrades on D, I just don’t see how all that adds up to ‘same or worse’

Is there anything other than blinding DA hate fueling these predictions?
