How can I even answer that?
Of course opinions are subjective and opinions will differ. However, if you had a group of 100 people that knew what they were talking about judging a performance then they're obviously not all going to differ. The odd one or two, sure. But the majority would reach a similar verdict.
Stats have their uses and in some cases can be used as an absolute way of judging something/someone (penalty conversion for instance) but a 90 minute performance is about so much more. A goal or an assist doesn't necessarily mean that player had a good game. The goal or assist is great though, obviously.
