And I quote you:

"Now they have the exact same offensive numbers except player A has 20 RBIs and player B has 710 RBIs. You're telling me Player B didn't have a better season. The only stat with any difference is RBI."

You really believe that the ONLY stat with any difference is RBIs? You need to educate yourself on the numerous statistics that are out there that tell the picture MUCH better than RBIs ever could. Player B would also have VASTLY better Rbat, RAA, WAA, Rrep, RAR, WAR, oWAR, etc. We haven't even began looking at all of the situational batting statistics either which would also show how Player B had a much better season, like BRS%.

This is what I mean when I say RBIs are worthless. A VCR in good condition will still allow you to watch a tape; a floppy disk will presumably still keep copies of your Word documents or other small files (if you can find a device to read it). These things technically have a use, but are more or less worthless now. We’ve got other things that do their jobs better, and do more besides.

It’s the same way with RBI and wins (and the like); these are “meaningless” and/or “worthless” only because we have other tools that do their jobs better, and more. A hundred-plus RBI might tell you that the hitter was probably good that year (not always), but also gives you a bunch of other information—opportunities with runners on, most obviously—and it’s impossible to separate the two. It’s like static or tracking problems on a VHS tape (to stretch that analogy to its very limits). We have many other ways of tracking things hitters do that lead to producing runs—ISO, TAv, and so forth—that also keep track of the good things, but that weed most of that other junk out. The same is true with wins; a lot of wins probably means a good pitcher, but also probably means a good team (or at least a good offense). Other stats do that better. None of them is perfect, of course, but better.

So it’s not that RBI and wins are literally “useless,” in the sense of having no actual utility. It’s just that, in a world with so many tools that have the same use but are much better at providing it, the old stats are of no practical use to us. Citing those stats in the context of a value discussion has no meaning, as long as we have more advanced and nuanced information available.
