Ol' Big was a skilled and tactical blind man working as the ball boy for the Running Rebs football team.
Origin
Ol' Big played football for a small school. Due to racism, he only was allowed to play against other small, colored schools. He broke all kinds of records and was one of the best at the game. One day after it was all over, he suddenly went blind. He learned that you might never be done with football, but football might be done with you.
Meeting Euless
Ol' Big started teaching football to Euless Boss. He took pity on the boy for being smaller and weaker than others, but admired his desire to get it done. The boy would remark that football was worth the blood.
After watching Euless not be drafted into college football, he watched Euless break down and murder his father in exchange to become the head coach of the team. He began to worry about what sort of monster he created.
After working with Euless for many years, Ol' Big killed himself when Euless killed Earl Tubb. He knew that football was not worth this much blood.
