At the beginning of his USC career, Eagles quarterback Matt Barkley befriended inspirational speaker and USC alum Louis Zamperini.
Zamperini ran track for USC, competed in the 1936 Olympics in Berlin and served the United States in World War II.
During Barkley's tenure at USC, Zamperini would often visit the Trojans at practice and offer words of encouragement.
In an interview earlier this week with CSN's Derrick Gunn, Barkley detailed the first time he met Zamperini and how Zamperini became an inspiration to him.
"He spoke at one of my freshman classes at USC," Barkley said. "It was a sports journalism class. He was a guest speaker. That was when he was 92. He came and spoke to our class about his life, his story, leadership, his history with sports. I remember my professor kind of hinted to stay behind and meet him because of how special he was."
Zamperini died from pneumonia on July 2 in Los Angeles. He was 97. His incredible journey through life became a best-selling book called Unbroken. The movie version of the book will be released later this year.
"Those who haven't read the book will see what true character is and what true determination and perseverance is," Barkley said.
