Before the WAR stat came to fruition, were what we used to evaluate players wrong? Are there guys in the Hall of Fame that don't belong because we overvalued them using stats like HR's, RBI's, BA, OBP, etc? Have we not been able to accurately determine how good a player was just by watching them play with our own eyes?
WAR is fun. It's about as useful as the old GWRBI stat. Both have their flaws. That is just my opinion.
