No, it says he looks at several that are out there but relies on his own internal formulas for actual usage. CubinNY is railing against the concept of scale in WAR. At least I hope he is, because nitpicking a specific weighting of inputs would be a really weird thing considering that there are multiple public forms of WAR we see used all the time. The quote from Mozeliak is pretty clear in that they use WAR as a concept, they just use proprietary inputs to try to get the variant they are most comfortable with. I'm with TT on this, yes Mozeliak is saying they don't use a WAR that we/public knows. But his quote, at least to me and TT, seems to assert that they have a WAR like model/formula that attempts to measure/accomplish what the WAR's we know about does and they do base decisions off of that. Their "WAR" just has a few more/less/different inputs of data and/or weighs things more/less than the public WAR's do. Debating about WAR being something that people use as the most important measure to make decisions is a completely different discussion, but it's pretty clear that the Cardinals are using something very close to the WAR valuation models that we know about to make decisions. Which was the initial statement that was being questioned about GM's/FO's not even thinking about/using WAR.
