Smokey Grays. Those were introduced in the Butch Jones Era when uni makers gave everyone a gray and before we had a proper black alt (something we had 100 years ago but hadn't had again until last year).
We had a black kit during Kiffin's year! I remember one of the things that annoyed me in the aftermath of that kerfuffle were people saying the black wouldn't come back because they were associated with him.
I like the Smokey Grey myself.
