How is saying a fact disingenuous? What a weird response.
I agree with all this and didn't suggest otherwise. He's a very good coach by every metric, both in terms of premierships won and other criteria by which a coach's success may be judged. He is already among an elite group of the best coaches the game has seen. Not disputing that much. All I'm disputing is the idea that he's best coach ever. I don't think it's unreasonable to suggest that when weighing up "best coach ever", that premierships won should be a relevant variable.
Using the fact he has two and others have three or four meaning he isn't as good as them is disingenuous and doesn't do much to explaining the flags or his coaching career.
I'm actually in the boat that he isn't the GOAT coach, not yet at least. But there are a lot of coaches who have the same and more flags than him I rate under him.
