Holy **** you have no idea what the **** you are talking about. This was about guys who took fights on short noticed. Your dumb ass brought up Vitali. He took it and lost. Again simpleton this is about a guy who took the fight short noticed. Your example prove my point in that the guy lost. Now you go on about getting beat and taking a lose somehow propels a fighter to greatness.
Let's say Andrade takes some early KDs, but recovers, loses rds, but survives. GGG wears down chasing him for a few, then Andrade catches GGG coming in, atypically off balance and takes a counter R hand that sends him to the canvas. Golokin tucks his chin, gets back to the front foot, but only behind a jab and the final 2 are controlled by Andrade. He loses a 115/110 decision, but shows the world the exciting fighter we know from his fights with Martirosyan and Nelson. Is that hurtful to his career??? Heck no. HBO would finally get him that 2 mil 4 fight deal and he could get another 2-3 big fights and a couple showcase bouts to build up the bigger ones. Lots of good can come from an L, especially if it's a short notice fill in
