Hitting theories have changed in a pretty significant way since Kingman's day - he led the majors in strikeouts with 156 in 1982. The last time that would have made the top ten was 2009 and the last time the MLB leader had less than 160 was 1995, 20 seasons ago. So if you don't accept a lot more strikeouts as part of the game, you're not going to like the current game.
WAR is a pretty good stat as a way to look at overall contributions, particularly when it's consistent with OPS, which it is in Wright's case. The postseason, particularly in his case, is a small sample size - you basically have 16 games so far, about 1/10 of a season. In 2006, he had a good NLDS and a not so good NLCS, but he did have 6 RBI in 10 games and hit a home run. But that's not his body of work - it's the whole 12 years, the hits, the runs batted in, the defensive plays, the Silver Sluggers awards and the Gold Gloves. If people don't remember Wright as by far the best 3rd baseman the Mets have had since 1962, then that's on them, not on him.
