I'm sure stats like that have their value, but I don't find value in something I have to look up to remember how it's calculated, or remember where I have to go to look it up. And if there is a mathematical equation to it, forget it. I really don't want to know that one. I love baseball as much as the next guy, but I really don't feel like mixing math with baseball. I can respect those people who value those stats, and the even more obscure ones. However, it's more than I really feel is necessary to place a value on a particular player. I think I can get a good enough picture of the value of a player based on OPS, OBP, SLG, OPS+, ERA, WHIP, K/9, BB/9, ERA+, etc. All stats that can be easily found at the sites I frequent the most for stats. I'll always read articles that discuss these newer saber stats. I am interested. But, it's too much effort for me to apply them as often as I apply OBP, etc...
