Stoops and OU President David Boren wrote the forewords.

"You may not appreciate just how great a victory he has won until you read the story, but trust me; he has endured tribulations that would have devastated many of us," Stoops wrote. "College coaches are often cited for the way they motivate others. Truth be told, it is often these same young men that motivate coaches. Eric was that kind of player for me. He has impacted my life in a positive way and I know he does the same for so many others."

Thunander said he penned "Silent Thunder" for himself.

"I was caught in the past and I thought maybe if I write it down and read it and put it inside so I can start moving forward ... because I was kind of hanging here in limbo," he said.

But along the way, he found when he spoke to individuals and groups, they would draw inspiration from his experiences. And it gave him a goal of becoming a motivational speaker. He now has a bachelor's degree from OU in communications.

"I hope I go there and open minds," Thunander said of his talk at the library Sunday. "Being a motivational speaker to me is when I'm in my element. Even though it's really strange, with me being deaf, I always have this urge to talk."

As a child, his hearing mother didn't want to learn sign language. She wanted Thunander to read lips and speak.

"She would force me to talk," he said. "You know, it kind of gave me a connection with the hearing world, but growing up with the environment I was in didn't help much either."

He went to mainstream schools in California and later in Lee's Summit, Mo.

But he also was a victim of abuse from two of his mother's three husbands, he said. He was moved from foster home to foster home.

When he was 13, he saw a story about Kenny Walker, a deaf football player for the University of Nebraska, who went on to play for the Denver Broncos in the 1990s. And he thought football might be something he could be good at.

So play football he did, priding himself on working "five times as hard as any other player." Thunander was ranked in high school as the 58th-best player in the Midlands by SuperPrep magazine. He registered 242 career tackles, with 90 tackles, two interceptions and two fumble recoveries as a senior at Lee's Summit. He was part of Lee's Summit's mile relay team that set the state record.

He was recruited by almost three dozen college programs -- until they would learn he was deaf and somehow forget him.

OU was the exception. Thunander was offered a scholarship and found a new home, something that surprised his Lee's Summit teammates, some of whom said he didn't deserve it.

But Thunander didn't believe them. He knew he'd outworked almost everybody for the opportunity to play university ball.
