I think lights out put it most succinctly after beating Thornton in Donald Mcrae's excellent Dark Trade
"An' now, baby, it's time to eat cheeseburgers, lotsa cheeseburgers...'cos I'm James Toney, champion o' the world..."

Imbued with patience and skill he spoke of administering " a respectful beating" that night.
The time has come to walk away from an exceptional career.
James "Lights Out" Toney. A Legend.
