In my opinion, Coach "turned the ship around" in the sense that he undid the previous regimes incompetencies and installed a great well-thought-out base for all the systemic intricacies which needed to be addressed in a Top-Ten program. ... this he did, efficiently and brilliantly. That was stage one.
Then several years of battling those previous limitations (and having the most bizarre bad fortune with alleged high-potential quarterbacks), he saw through the issues needed to establish the program one step higher. He did not "turn his own ship around" but he brilliantly refined what he had built. This is stage two.
What Coach has seen (apparently) is that the former way that his offenses scored like crazy against people at Grand Valley and Cincinnati would "work" at Notre Dame, but only if we got lucky with high-performing QBs and several game changer type recruits. Although we could get a certain type of game changer, it wasn't happening regularly. Top-ten QBs weren't either.
How to solve a very tough dilemma --- consistency in the Top-Six teams without Top-Six offensive stars? Kelly has said it more than once this year: We have found an identity, a system, which we can recruit to and fully exploit, and win games: BIG MAN FOOTBALL. BIG Lines. BIG Receivers. Power football in the air as well as on the ground with a savvy QB to run it.
This was not Coach's natural offensive tendency --- but the man saw it. He doesn't want us to be Wisconsin --- we will sling it, and the QB will run it. He wants us to be like an old style Derek Henry-like Alabama --- power at you all game but power in the air too, and here and there a bomb (and not by a Top-Six QB doing the throwing.) We can't get the BAMA wide flyers, so he got the BIGS.
Kelly is a gem. Don't know how he can stand up to the innumerable job demands. Fortunately, I have to believe that he never reads fanboards or anything like the crap which is spewed out in such media about him and his efforts.
