Well, there was this guy named Cremins. And he took GT to previously unseen heights (rankings, wins, exposure, championships, magazine covers - you get the picture). He brought blue into our picture with unis and the primary color of the Thrillerdome Floor.
At the same time, there was this pompous football coach preaching about everything under the sun except how to win more games. Black watch this / that. Even though it only applied to one side of the ball. But he looked good in his black & sunglasses. And never mind the 2 embarrassing games vs freaking Furman.
So a winner like Cremins (surprise) won out on the color scheme.
As for the new locker rooms, jeez people, it is not about Blue vs Gold vs White.
It is about what is the best way to keep the carpet looking Clean an Maintained.
