8. Bill Snyder
Snyder was an excellent college coach. He spent his entire career at the NCAA level because he never felt the need to step into the pro-game. A Kansas State icon, he rejected the NFL because he wanted to mold young minds. This proved to be a great decision because the Wildcats even named their stadium after him and his family.
However, the best coaches are also obsessive and eccentric. Snyder was no different in this regard. One of his wackiest traits was his compulsive texting. He was in constant communication with his athletes. In fact, some of them rolled their eyes because they received messages every 20 minutes. But he was responsible for a great program in Kansas.
