Corbitt was active during the Jim Crow era. His son Gary Corbitt talked about one particular incident in the mid-'60s.

"If you're not the flavor of the month, you don't garner the same contracts as white athletes and have to accomplish a lot more, I think it will be different moving forward," Gray said.
He's doing his part, through his organization Project Inspire Diversity. It is tapping into his contacts in the sport and getting brands committed to helping younger Black athletes.
"The way I grew up, the idea when I come up, we come up, we being each other up," Gray said.
