Been really busy, wanted to reply to this earlier. My post in a follow up was:
This will be the first real big test for our offense against an incredibly talented D.
And I stand by that. App's defense had some very good athletes but it was inexperienced, starting 4 freshman in the middle of the field and losing most of it's talented D-line to graduation. UND's defense was terrible, and OPSU was even worse. I don't believe the Grizzly offense has faced a more complete unit than NAU, hence "the first real test" and note if was for the offense against the D - I'm not saying for the whole team, that first test was App, the 2nd test was UND, and so on.
However I will say, PSU will be our first test against an option-based offense.
Beyond that I don't see any other "first" tests, then it gets into adapting to more familiar faces/schemes/teams.
