I dont think I would rank Iowa number 9.
Good thing they're ranked 8th, then, huh?
As for the rankings themselves, the main page doesn't really show much, but the preview page goes into more depth.

The only thing I really disagree with is that Murray is a such an amazing kicker. Yeah, he'll be remembered for that PSU kick in '08, but there is still a lot of weak spots. First, his leg isn't all that powerful. Kickoffs don't seem to travel past the 15 yard line, and I'm not entirely sure about accuracy for longer kicks. More worrying is the fact that people have noted a change in his technique, in that he's kicking more line drive kicks (perhaps to gain power?). While he was 19 of 26 last year, he missed a field goal in each of our losses, which when you consider the scores, could have been crucial in the long run.
As for Iowa State...
It looks like they're ranking you guys low for the following reasons:
1) Mistake prone QB
2) A weak defense last year, made worse by a new LB corp, and lack of depth on the line
3) Inconsistent kick game
4) A tough schedule that presumably lowers expectations for the team?
