"Its Texas," Miller told InsideTexas.com on the eve of the game. "Thats where I am announcing."
On Saturday, Miller did just that, committing to the Longhorns over Oklahoma and Utah with just over three minutes left in the second quarter.
"Its a great school academically," he said. "The coaches are great and so are the players. Texas is a great situation for me to play and thats where I need to be."
In Austin, Miller said he is looking forward to be "mentored" by the likes of Rodrique Wright, Larry Dibbles and Frank Okam.
"Thats real important to me," he said. "I really respect those guys and feel that I have a lot to learn from them."
For Miller, he said the attention he received from the Texas coaches throughout the recruiting process was instrumental in his decision.
"I really like the way Texas recruits," he said. "I appreciate the way the coaches treated my family."
Miller said he has high expectations for his freshman year.
"I definitely expect to play," he said.
Yet Texas might still have some work to get Millers signature on Feb. 2. He said he has been talking with the Oklahoma coaches this week and could have an in-home visit with them next week.
"Thats a possibility," Miller said. "You know, Im not really going to rule anything out." [IT subscribers click here for more on Miller and the Sooners.]
But at least for now and a nationwide television audience on Saturday, Miller is a Longhorn.
"Shoot, this feels good," he said. "Hookem."
