On National Signing Day, Samuel Clemens High School senior quarterback Frank Harris officially signed a letter of intent with UTSA, and he turned down some big-time programs before he did.

Frank had verbally committed to UTSA months ago and said he wanted to stay in San Antonio be close to family so that they could continue to watch him play.

"I appreciate them and I love them to death and I wouldn't be the person I would be without them," Frank said.

"When we first started doing the recruiting process, I told him, ‘Once you make a decision, that's it. Because this is a step to manhood and you have to show that you're a man of your word,’" his father Darrell Harris said.

Frank holds the school records for total yards, career passing yards, and career touchdowns. He is also an all-state football player. Upon taking the next step in his athletic career, he recalled his most memorable moment of his final season.

"Last year, we played Smithson Valley, ran back and forth the whole field. And so it happened that I scored. I know coach didn't want me to do that, but we scored so he wasn't too mad," Frank said.

But Frank has faced challenges midst his success. Toward the end of the season in his senior year, he was tackled on the sideline and tore his ACL. The injury took him out of the last three games of the season and he missed the playoffs. But that didn't stop big name schools from seeking him out.

He received offers from more than a dozen other schools besides UTSA, including Rice, Baylor and Georgia Tech.

Frank says that his love of football began at an early age, at 5 years-old. His parents told KENS 5 that they saw signs that their son was destined to play football.

"First time I saw him out there on the football field, playing flag, and he comes around the corner with a mouth piece wiggling and he ran a touchdown. I said ‘Ooh, we might have something special,’" his father recalled.

"He would train on his own. By himself, if there was no one else around," Frank's mother said.

As for his future plans, Frank says that he would like to play football in the NFL.
