Did Landry Jone, Ryan Broyles and the rest of the Oklahoma Sooners do enough to hold off Alabama and LSU for the top spot?
With a good, but not great, performance in a 38-28 victory against tough Missouri, Oklahoma most likely will remain atop the USA Today Coaches' Poll.
However, Southeastern Conference powerhouses Alabama and Louisiana State made viable arguments for taking over the No. 1 spot, as the second-ranked Crimson Tide wiped out visiting No. 12 Arkansas, 38-14, and the third-ranked Tigers went on the road to dominate No. 16 West Virginia, 47-21.
So, life at the top of the poll should look pretty similar in Week 5. But what previously unranked teams may have worked their way into the top 25?
Here is a look at three.
Case Keenum is one of the best quarterbacks in college football.
Led by Heisman Trophy candidate Case Keenum, the Cougars improved to 4-0 with a 56-0 victory against visiting Georgia State.
Playing not much longer than a half, Keenum threw for 415 yards and a pair of touchdowns, while the Houston defense was much improved, pitching a shutout after allowing 34, 23 and 34 points in its first three games.
The only potential bugaboo for the Cougars is their schedule, which hardly will remind anyone of LSU's.
Seen hitting Andrew Luck last season, Arizona State linebacker Oliver Aaron - a native of Gainesville, Fla. - has helped his team open 3-1.
Ranked 18th two weeks ago, the Sun Devils exited the poll last week after losing a close one to Illinois.
Now, after whipping previously unbeaten Southern California 43-22 on Saturday night, it might be time for Arizona State (3-1) to return to the Top 25.
The victory ended an 11-game losing streak against the Trojans.
Ron Zook's Illini may deserve a spot in the top 25.
OK, so coming from behind to beat visiting Western Michigan, 23-20, isn't all that impressive.
However, the Illini's body of work might be enough to earn a spot in the poll.
Already 24th in the AP rankings, Illinois has a victory against a quality opponent, having beaten Arizona State, 17-14, eight days ago.
It might be time for the coaches to take notice.
