By all means, include date to show your brilliance. You would have passed on a BF for "hundreds of others that were more qualified", and passed on the guy who showed in just a couple years that he is NFL quality.....not just college quality, but NFL quality.
It is just comical to me when freaking internet posters think they know more about coaching than guys that have eat, drank, and slept football for a lifetime. KF fully understands what it takes to be a good coach, and he KNEW that Brian was gonna be good one. KF proved to be right, you proved to be wrong.
