I actually began listing reasons why KF should quit this year. What I came up with were:
1. Currently still owns a solid reputation.
2. His kids are done playing for Iowa.
3. Already made all the cash in the world. What's a few dollars more if one isn't having fun professionally day to day?
Point 3 made me realize that KF will definitely come back. Because he is about to have a great deal of fun. He has made the changes (new OC, DC, assistant coaches), just needs time to reap the rewards. I look for a mega season next year.
