He's done an amazing job of updating his offense and really making it work again. I think he spent a lot of time thinking about what he would/should have done differently when he left for a few years.
Also, he's really changed his recruiting strategy. He's gone much heavier on prep players (that qualify) at this point. He's also going heavy with quality grayshirts, too.
I don't like his aversion to marketing. I don't like his loyalty to guys like Cosh. I hate his hiring of Sean.
Other than that, if this keeps up, I hope he goes Paterno. I at least want him to see us through Sams because that could be awesome.
