Great question. I'm not sure this question is best in the H. Dekkers thread, so I'll respond here.
I am not as familiar with the team, so I rely on what others think. I think It might be a good year though. Without specifics on players, our teams' success will again parallel the success we might have with the offensive line, as others have said repeatedly.
Beyond that, we need to continue our defensive tradition of the past few years, maybe even improve on it (getting more turnovers, not giving up big plays on 3rd down, etc.). Be sloid in ST's, kicks, punts, coverage. I'm hopeful our run game will continue to be a big positive. It will definitely be different now with Breece gone.
I will of course, default to the obvious, QB play. It's very possible this, Hunter's play, along with our receiving core, could be a huge plus for us. I hope so.
For sure it is going to be a different team, but exciting for many reasons. Hope it turns out great! At the very least, I hope for another solid Bowl game at the end.
