Call it whatever you want, I see a pedestrian offense. ND walks while other teams run.
I've watched it for 10 years. Kelly runs the same plays he was running 10 years ago, the same plays he was running at Grand Valley, CMU and Cincinnati. It isn't a mystery why he cannot recruit elite players at the skill positions on offense.
I've been in the stands when fans from opposing teams can accurately predict the plays. I've see the almost total absence of misdirection. I've seen the jump ball/fade/back shoulder approach for what masquerades as a passing game. I've seen rbs run down from behind on slow developing wide running plays. You rarely see a play (any play) that surprises a defense much less an overall offense approach/series that confuses a defense.
There is a lack of adaptation, cleverness, imagination and innovation on the offensive side of the ball.
