I'm sure you don't apply this logic when someone has LeBron as the GOAT, nor do you apply this to anything else.Imagine disregarding the credibility of people who ACTUALLY competed against these guys. Their opinions are the only that matter to be honest. Get of your high horse brodie, you're an armchair critic, a mere spectator--just like the rest of us. So yes, their opinions have heavier value than your's, anonymous guy behind a keyboard.
Unless you've made Grammy-winning albums or an Oscar-winning film I better not see you in the Booth or Film Room critiquing anything.
