After three weeks, there are 33 unbeaten teams left in major college football and eight of them are playing against each other Saturday.
There is a Pac-12 showdown, with No. 7 Southern California visiting Oregon State.
In the Big Ten, Maryland should provide No. 4 Michigan its first real competition of the season.
No. 5 Clemson and No. 21 Wake Forest square off in a key ACC Atlantic Division game.
And then there is Duke at Kansas in the most unlikely matchup of 3-0 teams. The basketball powerhouses combined to go 5-19 with one conference victory between them last season.
The winner Saturday will be two-thirds of the way to bowl eligibility. It is a fascinating matchup and one of the five most intriguing games of the weekend:
No. 10 Arkansas vs. No. 23 Texas A&M at Arlington, Texas
Can Arkansas' shaky pass defense, which ranks last in the Southeastern Conference in yards allowed per game (353) and per pass (8.5), be the tonic for an Aggies offense that has had a hard time staying on the field? Texas A&M had won nine straight, though mostly close games, in the series before the Razorbacks snapped the slide last season.
LINE: Texas A&M by 2 1/2. PICK: Texas A&M 26-21.
Kansas State at No. 6 Oklahoma
This was lining up to be a bigger game until the Wildcats were upset at home by Tulane last week. Still, the Sooners have hardly been tested under coach Brent Venables and K-State has been a problem for OU recently. Four of the last five meetings have been decided by seven points of fewer, with two Kansas State victories.
LINE: Oklahoma by 12 1/2. PICK: Oklahoma 31-24.
No. 5 Clemson at No. 21 Wake Forest
Wake Forest won the ACC Coastal last season, but still couldn't handle Clemson in what was a down year for the Tigers. It was the Demon Deacons' 13th straight loss in the series -- the last four by an average of 38 points. Clemson has eased into its 3-0 start. Can Wake provide better insight into the Tigers' ceiling?
LINE: Clemson by 7 1/2. PICK: Clemson 31-21.
No. 7 Southern California at Oregon State
The Trojans have been landing on this list a lot as we try to get a handle on just how good Lincoln Riley's portal all-stars can be. The Beavers are built to exploit USC's issues up front on defense, but can they keep up with QB Caleb WIlliams, WR Jordan Addison and a Trojans offense averaging 7.96 yards per play (fourth in the nation)?
LINE: USC by 5 1/2. PICK: USC 35-28.
Duke at Kansas
Jayhawks coach Lance Leipold looks like a miracle worker in his second year leading a program that has not won more than three games in a season since 2009. Kansas is the third-highest scoring team in the country at 53 points per game. Duke has already matched last season's win total under first-year coach Mike Elko. Can a football game fit in Phog Allen Fieldhouse?
LINE: Kansas by 7 1/2. PICK: Kansas 38-24.
