I agree that most people's eye tests match the data and facts.
When people start saying things like So-and-so is an above average defender, I wonder how an eye test, alone, can lead anyone to a solid opinion- one where they feel very confident they are right.
Without watching other players almost every game, how can anyone ever know, without using some sort of data?
Maybe some watch a 5 games a day, but I don't know anyone who does, and that might only be 1/3 of that day's games.
There are certain opinions that can be fact-checked, pretty easily, but sometimes, there can be different data used, or different sample sizes used, and that opens the door to legitimate differing opinions.
Some statements like JD hits in more Dps than anyone else on the Sox can be proven or disproven by facts. Statements like Bogey is an above average fielder is open to debate and differing data.
