THe idea that scouting would disappear is a slippery sope argument. Not to mention, "eye test" from scouts and "eye test" from fans are two entirely different things. Don't take it personal. That encompasses all of us. But as a fan, you tens to watch one team and see one shortstop, centerfielder, etc. play 150 or so times. You see other shortstops, centerfielders, etc. play 6 to 18 times tops. That sample size makes for a poor evaluation, especially since the eye test inevitably turns into comparasion or worse yet, superlative. I bet somewhere on this board, possibly from you, but also others, I can find someone referencing Jackie Bradley as the "best centerfielder in the "AL, or possibly "in MLB." How much time did these people spend watching Kevin Pillar or Kevin Kiermaier? Have they ever even seen Ender Inciarte or AJ Pollock? And yet somehow, this is the conclusion.
Heck I live in Cubs Country and people out here think Dexter Fowler is an elite defensive player based on the eye test. And I am quoting the evidence here "I don't care what the metrics say. I watched every Cub game and saw him make more great plays than any other center fielder~" And THAT is supposed to validate it?
