Pujols is Alex Rodriguez, circa 2006.
I mean we have to realize every hitter has a down year even if it isn't marred by injury. Pujol's down year might be 2007, but even Arod's down year was great for 99% of MLB hitters out there. Of course one down year shouldn't mean you drop a few spots down from say #1 to #6 and a career year slides you up far because you know that he'll repeat or better that year because it's not a career year but a trend.
(Arod vs. Soriano vs. Howard).
