Oakland Raiders fans - what has happened?

I've watched every second of the last five games. The macre in Denver, the destruction against Seattle, and the come-from-behind underdog win to KC. 2nd in the NFL for rushing yards/game. Suddenly, we go on a bye, and have lost the last two. Last week WAS expected by me, but NOT by 32 points. That's unacceptable. I know that Pittsburgh's run defense is good, but is it really THAT good? Because that was pathetic beyond belief. And then today, we lose to an injured Miami team 33-17. Don't get me wrong, Miami is a good team. But the score should've been a lot worse, especially because of McFadden's stats. In case you missed it, here are his stats (couldn't even make this up if I wanted to): 8 rushes for 2 yards. Miami is 19th in the NFL for stopping the run!!!!! What has happened?!?!?!? INSIGHT?
