I looked back at the betting line archives all the way back to 1985. This week is the 1st time Iowa State will be a Touchdown or less underdog against a Top 10 team. They have obviously never been a favorite. The only 2 times the line has been 10 or less was Iowa in 2005--line was 9.5 and @Oklahoma in 2002--line was 8.5. Those outcomes were drastically different.
Bottom line, this is the best opportunity for Iowa State to win a game against a top 10 team in quite some time.
