Road games sort out the contenders from the pretenders.
Several highly ranked teams play away from home Saturday for the first time this season, including No. 1 Alabama, No. 6 Texas, No. 8 Nebraska, No. 9 Iowa and No. 10 Florida.
If last week was about marquee matchups, this week is about upsets — or at least the potential for upsets.
The Tide expects to have Heisman Trophy winner Mark Ingram back for its trip to Duke. The Blue Devils (1-1) have been competitive under second-year coach David Cutcliffe and quarterback Sean Renfree has thrown for 708 yards in two games this season.
"This is a very dangerous team because of their ability to throw the ball and score points," Tide coach Nick Saban said. "They scored 48 points last week on a team that has been ranked in the top 20 most of the last five years in Wake Forest."
True, but Wallace Wade Stadium is not exactly Cameron Indoor. In fact, it wouldn't be surprising if about a third of the 34,000 or so fans in the sellout crowd are rooting for the Tide. Anything less than a lopsided victory by 'Bama will be a surprise.
For some of those other national championship hopefuls, the road figures to be bumpier this weekend.
Texas visits Texas Tech (2-0) for Tommy Tuberville's first Big 12 game as Red Raiders coach. The last time the Longhorns went to Lubbock they were No. 1 in the nation, but Michael Crabtree broke their hearts with a last-second touchdown.
Nebraska goes out of conference with its first road game of 2010, traveling to Seattle to face Jake Locker and Washington. The Cornhuskers will counter with redshirt freshman quarterback Taylor Martinez, who has been excellent in his first two games. The Huskies, however, will be much tougher than Western Kentucky and Idaho.
Florida faces rival Tennessee at Neyland Stadium on Saturday. The Gators finally found some offense in the second half of their 38-14 victory against South Florida last week.
Iowa might face the toughest test of all Saturday night in Tucson against No. 24 Arizona. The Hawkeyes beat the Wildcats 27-17 in Iowa City last season in a game that wasn't as close as the score.
