Although a fighter isn't proven until they beat an opponent of note, some of us aren't afraid to make a judgement based on what they see in front of them. The knowledgeable among us are well aware that you don't truly know, a fighter's true ability until it has been appropriately tested, but as I pointed out in a previous post, sticking with a gut feeling about a fighter isn't necessarily a bad thing - you may well be wrong, but who cares. Some seem almost afraid to do so, and are limited to commenting on a fighter's level AFTER we find out, akin to South Park's Captain hindsight https://www.youtube.com/watch?v=esXJN_OTkmU
