"Coach (Jarrett) Anderson from TCU offered," said Antoine, who had returned from an official visit to Fort Worth less than 24 hours earlier.
"Coach Anderson said they would love to have me with their program. I feel great. The visit went great. I loved the players and campus. TCU is a great school."
Antoine was hosted by Kolby Listenbee.
"(Listenbee) said it's a great program at TCU," Antoine said. "He called it a brotherhood. I saw (Louisiana product) Kenny Cain when we were out during the weekend. He's a big swole guy.
"I met all the Louisiana players. They're all cool. I hung out mostly with No. 17, Sam Carter. The campus is beautiful and we were treated like royalty. It was beyond what I expected."
Antoine said the staff hasn't indicated whether they intend to utilize his talents on offense, defense or both.
"They want me for slot and defensive back," the first-team all-state performer stated. "My family loves it - that I committed to TCU. My dad really loves it.
"My coaches at Loreauville are all happy. I want the fans to know I'm going to give it all I got when I get to TCU - and help elevate the program even more than it is now. I'm also going to stay humble."
Antoine still has one hurdle remaining with his test score, which needs to be increased by a slight margin.
"I take it one more time next weekend," he said of the ACT. "The coaches are taking a chance on me, and I know they must respect me a lot to do that.
"This is one of the best days of my life."
