I would counter by saying it hasn't even been implied.
Most of these WAR arguments start with someone saying how useless the new statistics are because they don't agree with them for one reason or another, including this very thread. Some do start with other logic, such as when people were angry omit the omission of Bradley from the Gold Glove, and UZR and dWAR were brought into it. But the arguments against Bradley for Gold Glove all had the same flaw that had NOTHING to do with sabermetrics or advanced stats - none of us had seen enough of the other candidates to refute their nominations.
The problem is, the non-sabermetric crowd to me appears to be taking the stance "I don't like these new stats because they don't always agree with what I see." And they ignore the obvious reason for that - because they see more. Many of them are based on floating baselines of replacement level or league average. But rather than taking the opportunity to enhance the appreciation of the subtleties of the game that they can capture with their own eyes, or look at certain aspects of the game in a new way, or using them to decide to explore seeing other players (Andrelton Simmons became a must-see for me after I saw how he was destroying MLB with defensive metrics, and wow. The man does not disappoint.), it instead turns into a giant pissing match with a bunch of fans deciding they know more than the stats and stats guys, and already have their pants down, rulers out., with their high school baseball war stories at the ready to back them up. And heresy to anyone who dare try and bring up these new-fangled numbers. Their very existence is a personal insult to my expertise!!
And oh my God, try and explain some of these advantages of new stats over traditional stats and over eye test. I think Galileo had an easier time with heliocentricity.
