A couple interesting observations from this blog:
2. If the Harris Poll was to be free of preseason biases, how would you explain the fact that Oregon is ranked No. 23 and Cal at No. 21? The Ducks just destroyed the Bears by 39 points. The two teams have identical records at 3-1. And Oregon played a considerably tougher schedule than the Bears did, with games against three ranked opponents. If the Harris voters indeed voted on the basis of pure performance, there is no way that Cal should be ranked ahead of Oregon. ... The same goes for Penn State being two spots ahead of Iowa.
3. The credibility of the Harris Poll is again highly questionable, with voters putting teams like Iowa State, Kansas State, Washington and Texas Tech in the top 25.
