This new offensive staff is basically a black box given the Saints' injury situation last year rivalling ours from 2017. But the work they did before that wasn't exactly inspiring.
Well, New Orleans had a grand total of 3 games with their core offensive weapons (1, 2, & 4) but they also have that chunk of games with Marquez Valdes-Scantling (weeks 9-13) taking over as WR1 for Rashid Shaheed that I think gives a pretty good look at what they wanted their offense to look like.
If that 7-game sample of the Saints with their core weapons represented a 'real' team, they would have been a top 5 offense. (#6 in points per drive, #1 in scoring rate surpassing both Detroit and Washington).
Obviously, there is a ton of caveats with this kind of analysis. It ignores that other teams faced varying degrees of injury as well, it also only considered injuries sustained to offensive skill players (not the Offensive Line), and of course pulling a sample of opponents isn't the same as an entire season of opponents for a variety of reasons.
That said, I'd say the takeaway from when they had their weapons (or a reasonable facsimile thereof) on the field is encouraging to point to as a hypothetical ceiling when everything is clicking.
Overall, though, seeing moves like this to me represents the best part about having an established NFL OC come on (vs. a college guy or an assistant taking the step up) is that he has an established system AND he's got a bunch of guys who already also know that system, which I think will improve how well they can install this offense.
I mean, at this point, we've got the OC, O-Line Coach, QB Coach, and if we add Dennison here that'd be at least two other offensive assistants (including a former PLU QB) who all just worked together on this offense last year. It's never great to be changing OCs for the third time in as many seasons, but this is about as much continuity as you could possibly get.
