1. Bill O'Brien - There's not a coach out there who has gone through what O'Brien has, and it is O'Brien's 1st year. Other programs could recruit his players and commits without interfering, and he lost some key players. He lost to a strong Ohio team and on the road vs Virginia. But since then, PSU has done better than expected.
2. Mike Riley - Last year, they went 3-9. 2 years ago they went 5-7. 3 years ago they went 8-5 (8-4 with a bowl loss). I imagine the last time they made the bowl game, this year's players were not key players. They are undefeated against a schedule that isn't easy.
3. Bill Snyder - It's probably not a huge surprise that KSU is undefeated. They have been good and had some big wins in previous years. Their QB is in Heisman talk. But K-State doesn't have a buffet of 5-stars like Notre Dame or Alabama. They don't have that tradition. Snyder has taken sub-elite talent out of high school and is having them playing at the elite level.
