Last year on offense we had a new HC, OC, WR coach, RB coach, OL coach, a new starting QB, and one of our top 2 RBs transitioned from WR to RB in the middle of spring practice, and we still had an OFEI of 33. We also led the conference in rushing, 3rd in total offense, 4th in scoring, and 5th in passing. We did all of that with a QB who was tied for the 2nd most INTs in the entire country.
Literally all of the staff is coming back, Jamal Haynes will have a full season and spring/summer practice of RB experience, Haynes King likely improves, and the entire system will be more open now that everyone is comfortable with each other.
I don’t see how you can look at all that and think the offense doesn’t at least remain stagnant.
