"Not a mismatch" is not the same thing as "about equal."
Texas and Iowa should be a mismatch, as is reflected in the 11-point line; in contrast, UT is favored by 4.5 over Penn State, which is about what you'd expect on a neutral field when one team is perceived to be better but not a lot better than the other. If there were the massive gap between the two teams that you think there is, that point spread would be a lot bigger.
Explain to me, how the point spread is a good indicator of how good a teams is.
Gamblers want money equally betted on each team, and they set the point spread in order to achieve that.
Funny how you totally ignore the poll data, which the entire BCS is based on; and instead use a point spread, which is what gamblers set in order to see equal money placed on each team, to determine which team is better.
