DeForest has stepped back to run the special teams and is replaced by Keith Patterson. It looks like he'll keep the 3-4 and tailor a few things to his teachings. Even when put together, those little things won't amount to the biggest change to happen under him or even around him.
The Mountaineers don't want a repeat performance in 2013, but it has very little to do with the way they play the game. It's all about the way they treat it. Last year, it didn't mean as much to them as it should have.
"I thought that's how it was supposed to be," said Cook, who wound up starting the final three games last season. "Then as things turned and the turmoil went down and the way things changed this year, I feel like this is the direction we need to go in the future."
The coaching staff is teaching lessons about the history of the program. Cook's coach, Tony Gibson, shared an intimate story about his father's job in a coalmine, and many players realized they'd never taken the pre-game Mountaineer Mantrip seriously.
Even in practice, there are new and restored features, like the pursuit drill that forces the defensive players to turn and rally to a randomly placed ball to illustrate their desire. It feels right again and not long after it felt so wrong.
"Just the whole feel of it, it's not explainable," Cook said. "As far as guys who have been here and know how the old defense used to be and how we used to carry ourselves and how we used to practice and everything else, there's a similar feeling."
Cook won't promise everything will be better. He knows every team in the country looks good flying around the field in spring practice drills. He's heard teammates and peers say in three springs previously that everything is different and improved from where it had been before.
In an honest moment, he says he doesn't know what will happen in 2013 and admits it is way too early to offer guesses about the future.
He just knows WVU won't repeat history.
"I've been here five years," he said. "I know when things are going in the right direction and I know when things are going in the wrong direction. I honestly feel now like we're going in the right direction."
