What's the difference between No.1 and No. 20?

What's the difference between the top-ranked team in the nation and the 20th-ranked collegiate football team?

Well, we are about to find out on Friday when the Arizona Wildcats travel to Oregon to face the Oregon Ducks. It'll be Arizona's defense against the rush against the Ducks' minute-to-minute scoring machine. As of this morning, the gap in the Pac-10 standings between Oregon (10-0, 7-0), 7th-ranked Stanford (10-1, 7-1) and the Wildcats (7-3, 4-3) is huge. Nick Foles and the Wildcats' offense...and Ricky Elmore and the Arizona defense needs to close that gap on Friday.
