Wrong, it shows that Quillin made good money compared to some contemporaries who weren’t necessarily worse than him. You really need to start reading books or go to school.
Quillin making more money than Korobov has what exactly to do with boxers not taking their entire purse home again? Do you think you are telling me something new here? The level, or ranking, a boxer has means NOTHING to his purse FFS... if you need to argue with someone just for the sake of arguing, do it with someone else. Too much has already gone over your head in this.
