Ferentz's teams have been designed to keep them in games against better teams and have overall success. That strategy has also allowed teams worse than Iowa to stay in games with them and from time to time beat them. In the end you get around 8 wins a season with some peaks and valleys. When you aren't Alabama or USC it is a good strategy as long as everybody buys into it and is ok with being boring at times. Which is hard for fans to do in this day and age and sometimes players as well.
