There are few certainties left in this young college football season -- four more top-10 teams fell this weekend, making it nine on the season -- but there is one thing you can take to the bank: Iowa's defense.
The Hawkeyes brought a top-15 scoring defense to Happy Valley on Saturday night and proceeded to hold No. 5 Penn State to its lowest scoring total in more than two years in a 21-10 upset

Expect plenty more field goals and safeties en route to Pasadena.
