Another of his sons, Eric, has battled inoperable brain cancer since he was 18 months old.
Holloway, who was close in age with Eric, was Eric's best friend.
“He was one of those who was always there for us,” Tracy Holland said. “He was like a son.”
Former Tulsa offensive coordinator Herb Hand twice broke the news to Holloway that he had cancer and joined TU players in shaving their heads in support.
“THE toughest fighter I have ever known,” Hand wrote on Twitter following Holloway's death. “Your impact on Earth is immeasurable...I love and miss you.”
During a 2009 Tulsa football game, T-shirts were given out with Wilson's number and “Just Keep Smiling” on them.
“You never saw the guy not smiling,” Tucker Holland said. “Wilson was a person who was bigger than life itself.”
In addition to the Courage Award, Holloway was a recipient of the 2010 Wilma Rudolph Award and was a finalist for the 2010 Uplifting Athletes Rare Disease Champion award.
“He lived a great life,” Tucker Holland said. “Everyone loved him. I never knew another person like him.”
