Maybe it wasn't the uniforms
When Steve Spurrier did a terrible job of coaching the Redskins, I thought he had a psychological barrier to coaching them well. After all the logos look alike. The colors are similar. Maybe on some subliminal level he thought he was coaching Florida State instead of the Redskins.
Now, he is having a hard time coaching South Carolina's Gamecocks. Apparently South Carolina is the college football coaches graveyard. Spurrier looks much younger than his 60 years, so he can still have a career in sportscasting.
