Bob Stoops' visor carries two familiar markings – the interlocking OU and the Nike swoosh.
And one not so familiar.
Off to one side, Stoops attaches a gold ribbon pin, denoting neuroblastoma awareness. Neuroblastoma is one of the most common solid tumors found in children under 10.
The pin is a promise to Cody Brown, an 8-year-old boy who died from the disease in 2003.
Stoops, his wife Carol and former Sooners' Jason White and Jonathan Jackson were at Brown's bedside as his fight with the cancer neared an end.
Kay Tangner, a volunteer with the Children's Hospital at OU Medical Center, recalled the story.
"Cody was at home, really sick,” Tangner said. "At the very end, Cody asked Coach Stoops, ‘Coach, where's the pin I gave you?' He wasn't wearing it.
"And he said, ‘Well, I don't have it on right now. It's at my office, on my desk. But I'll wear it. I promise you I'll wear it.'
"He's worn one on his visor ever since.”
Inside the Switzer Center, there's a display case featuring a pinned visor and a nod to Brown, described as "a brave young man and a Sooner fan of the highest order.”
