I have no idea why you're trying to argue WAR is anything other than a counting stat. It is an attempt to measure actual player contributions over the course of the season. Like UZR can be displayed in terms of UZR/150, you could make a similar metric for WAR, but each of those have decided drawbacks. WAR is not supposed to be used as in indicator of future performance - there are many better metrics for that. 2010 MLB average BA is .259. I've seen standard deviations for BA estimated at .027. So this year I would consider anything in the neighborhood of .245 to .275 to be decent. And I meant to say its near impossible to sustain a good OBP without a decent BA. The league leader in BB% is Berkman at 16.2%, which allows him to post a good OBP (.361) despite a somewhat poor BA (.237) However, players with obviously poor BAs couldn't sustain a good OBP even with Berkman's exceedingly high BB%. Reynolds (13.2%, .214, .330) and Carlos Pena (14.6%, .212, .336) are merely able to get to average OBP despite all of their walks because of their poor batting averages.
