Cal just stated in his Post-Game PC that he doesn't even consider playing a kid until the kid says he's ready to go in a game.
So even though Vanderbilt has been practicing and going through pre-game, until he tells Cal I'm ready to play in a GAME, Cal will not play him.
Cal also stated that he does't even work with the players that are injured. So, until Vanderbilt says he's GAME-READY, he won't even be in the gameplan. Cal even went further and said there comes a point that he will shorten his rotation and if a player can't go, he'll go with who can play.
Cal sounded like Jared is at a point of play soon or it won't matter if you are ready or not.
