kelly knew the line sucked, made some adjustments to it, and changed the entire scheme of the offense allowing ND to play really well the last 6-7 weeks. In 2021 kelly/rees wanted to run the ball and have a lot of downfield PA shots. The line struggled, and coan had poor pocket presence resulting in sacks and not getting the passes off, so they flipped to a quick pass offense with a lot of RPOs (not qb run rpos though). IMO it shouldn't have taken Kelly to the end of the vtech game to make these adjusments, it was clear vs toledo and purdue despite the wins.
This year, ND did not identify how bad zeke was playing and make a change, he got injured forcing one. ND did not change the offensive structure until it was too late after week 10 when it was obvious from week 4 on how teams were defending ND, and the weakness with Zeke, the guards inexperience, and wrs. This years game plan was to run run run, and be at worst in third and short allowing Hartman to disect the d and make simple passes or even run the ball with estime on 3rd and short. This scheme would also create some big runs in the run game. The issue, teams decided to load the box and take away our constant first down runs getting us into second and 10. Parker never ever adjusted and ND vs good teams lived in 2nd and 9 or 10. That's not a recipe to march down the field, a few times we did, but it's why we had so few tds vs Duke, louisville, OSU, Clemson. What should have happened is ND PA on first down more allowing for more crossers and passes over the middle due to all the congestion sucking the LBs and even safeties in. To parkers point, it's hard to PA on 2nd and 10 or 3rd and long, but he got us in that situation.
