He said that his relationship with the coaches at TCU would weigh heavily on his decision.
Just two days after finishing his official visit, Calvin chose the Frogs over Wake Forest.
The TCU coaches have told Calvin that they would like him to play boundary corner and match up against the physical outside receivers in the Big 12. "I feel really good. I prayed about it, and it just felt like where I needed to be," Calvin said of TCU. "My parents kind of wanted me to go to Wake Forest, but I felt like TCU was better."
"I feel like TCU is where I needed to be."
Wake Forest was Calvin's first offer in late November, but Calvin said he is excited about the relationships he has formed with players and coaches at TCU.
"With Coach Jennings and David Jenkins, it feels good. I am really excited. I am ready to go there and work hard. I can't wait to get on the field and show people what I can do," Calvin said.
With his commitment to TCU, Calvin will be playing with one of his high school teammates, Ranthony Texada, who also will play cornerback for the Frogs.
Calvin said he and Texada never dreamed they would be able to play together at the next level.
"I talked to Ranthony; he is really excited," Calvin said. "We never expected this in a million years."
"It feels good because I grew up watching Texas and OU. I watched Kansas, Kansas State, and Oklahoma State. It feels great that I can be a part of that and actually play."
Calvin says he plans to live in the weight room before he gets to TCU's campus in the summer.
"I just need to get bigger, faster, stronger. I have to really spend time in that weight room and fall in love with that weight room. That is what I need to come in and help right away."
