No, they weren't worn this season, and they are the smokey gray, not black. They were originally supposed to be worn in the SEC Tourney final IF South Carolina had made the game. Since TN was the #2 seed, they would have worn the "away" uniform, which would have been this. Since KY beat USC, TN had to wear white.
Then, they were going to be worn at the Final Four had we made it, which we didn't. They will probably be worn next season though.
The coaches and players wanted to save them for a big game.
According to an interview she did with Maria, she will be #10 this season and will take #11 when Cierra graduates. Her dad wore #11 and her brother wears it, too.
