Sometimes these teams are ranked so high in 1 category and so low in another is because they suck in that 1 category they are low in so teams do not bother even going the other route. I mean the Vikings were so terrible against the pass.. why would you bother running? Same (in reverse) with the Raiders. In other words, while I think the Raiders are decent against the pass, their rating may be overstated because noone bothers (and they're always behind, so people run out the clock).
