In his weekly visits to Children's Hospital, Wilson saw what can be done with immunotherapy treatment, leading to him captaining the Strong Against Cancer initiative.

"The past three years being in Seattle, going to the Seattle Children's Hospital," Wilson told ESPN's Marty Smith. "But the one story has to be why Strong Against Cancer occurred, the whole emphasis for Strong Against Cancer. There's this kid named Milton, he was 19 years old, about a year and a half ago. African-American male. Very good-looking guy, a model, played quarterback. And he had cancer three different times.

"And at 19 years old they told him he only had 24 hours left. The doctor came in and told him there's really only one more thing we can try, and we're thinking about trying. It was a whole idea about taking the T cells out of a child and regenerating, re-energizing them, and putting them back in. Within two weeks, Milton was healed.
