Stating that self-help books are garbage is your opinion and you're entitled to it. Depending on your perspective the article could be in the self-help category, but I'm assuming you aren't a CEO or a business owner so that probably wouldn't apply to you. However, I do disagree with the your opinion towards self-help books. It's all a matter of how you apply them. Millions of people have read Dave Ramsey's book Total Money Makeover. Is it garbage? Absolutely not. It all depends on whether or not the reader has the ability and discipline to follow through with his recommendations. If they do then it will pay dividends in the long run. If they don't then they probably consider his book "garbage".
You and I actually agree on a lot regarding the state of Iowa football and Kirk Ferentz. His methods and strategy were exactly where they needed to be when he first came in, and it was just what the program needed in order to turn it around. However, the game has changed in many ways since then, and Kirk has struggled to adapt to these changes. Certainly part of that is his stubborness to adjust and admit that changes needed to be made. Because he dragged his feet in making changes I believe the program started to slip, and ulitimately it has ended up where we are today. The current state of the program has forced Kirk's hand. He's making changes as best he can. Whether or not these changes prove to be what is necessary remains to be seen.
The difference between your perspective and mine is that I have always believed, and still do believe that Kirk Ferentz is a great leader of young men. I think you'd be hard pressed to find someone who leads college aged kids as well as Kirk does. His organizational skills are second to none. That's a fact that has been pointed out by many elite coaches in the football world. He goes about things the right way, and his main focus is on turning these kids into men first and football players second. That's why I've remained loyal to the idea of him being Iowa's head coach. He's showing that no matter how stubborn he can be he's willing to make changes. Maybe in the long run these changes will ultimately mean his demise, but it won't be because he's a poor leader. It will be because the game of football changed and he couldn't figure out how to adjust quick enough.
