For reference, Pujols' 5.1 WAR this season was as good or better than 4 of Fielder's 6 seasons. Also, after a slow start, he hit .316/.383/.571/.954 over his last 520 PA's this year. Those numbers surpass Fielder's 2011 when you include park factors. That's the big difference. When Albert slows down, he puts up Prince Fielder seasons on the way down instead of Ted Williams seasons. When Fielder slows down, he puts up Dmitri Young seasons on the way down. I realize much of that, but my concern is that this season could represent a trend. That .954 would still represent the lowest OPS of his career. He could rebound, but you can't simply dismiss the possibility that he could drop off in a fairly precipitous fashion. I'm not saying he will or that such a decline is even likely, but this year threw up a red flag. And you can't dismiss the age factor, either. Yes, it's gonna be ugly when Prince hits the downslope. But how far away is Albert's decline phase relative to Prince's? Albert may already be in his. When camps break, Fielder will be 28 and Albert will be 32, and Prince sure as hell won't be getting a 10 year deal from anyone like Albert might. Don't get me wrong, I'd be tickled to see Pujols in Cubbie blue in 2012. But I'd be a little less confident about what that meant in the long term than if Al had posted numbers a little closer to his career marks in 2011.
