WAR calculates the total number of wins that any player adds to his team over the course of a season by comparing the player's performance with that of a fictitious replacement. A "replacement player" is assumed to be an average Triple-A callup who might appear in the majors only as replacement for an injured player, and whose hitting/fielding or pitching skills are far below league average. According to Baseball Prospectus, a team consisting entirely of replacement-level players would likely be historically bad, winning only 20-25 games over a full 162-game season.
Seems to me that the REDS have had a lot more wins since replacing Adam Dunn!
That is pretty spurious reasoning. It's not like the Reds are the same team since Dunn left. Just ask yourself this question....would the Reds be better with Hamilton in center? The Reds have won more since he left.
BTW....RISP over a short period of time has proven to be a rather poor predictor of a player. The vast majority of hitters over their career have RISP numbers very similar to their overall production. Hence why it is not used much in the evaluation of players. At best you may find a few anomolies over the lifetime of a player. In the case of Adam Dunn, his career OPS wRISP is .897 and overall career OPS is .907. His BA is slightly lower, but that may be due to being pitched around some w/RISP. Anyway, you will find that trend similar across the league. RISP numbers will normally end up within statistical variance of a players overall stats. Hence why it is not used as an evaluator for the majority of players.
