Some things to watch in Week 2 of the Big 12 Conference:
Game of the week
No. 9 Iowa State vs. No. 10 Iowa. The Cyclones' instate rivalry game has never been so big. Both teams are ranked in the Top 25 for the first time when meeting in the Cy-Hawk rivalry game, set for its 68th meeting since 1884. Iowa State has won its last six home games, and Iowa is looking to win five games in a row against ranked teams for the first time since 1960. Cyclones running back Breece Hall, the nation's leading rusher last year, had only 69 yards rushing in the season opener. But he still extended his school record of consecutive games with a rushing TD to 13, the nation's longest active streak. Iowa State has given up only 16 total points after halftime (2.6 per game) in its last six games.
Best matchup
No. 16 Texas at Arkansas. The former longtime Southwest Conference rivals and future SEC foes both have top running backs. Texas sophomore Bijan Robinson opened the season with 20 carries for 103 yards and a TD, and had four catches for 73 yards and a score. Trelon Smith, the former Arizona State transfer for the Razorbacks, had 22 carries for 102 yards in the opener. This will be only the sixth meeting in the series since the Razorbacks left the SWC after the 1991 season for the SEC, where the Longhorns will join them no later than 2025.
Inside the numbers
TCU, which hosts California, is 7-0 against Pac-12 teams in Gary Patterson's 21 seasons as head coach. The Horned Frogs beat Cal 10-7 in overtime at the 2018 Cheez-It Bowl in Phoenix. ... After its first win in 679 days, though over an FCS team, Kansas will try to win consecutive games for the first time since September 2018. The Jayhawks play Friday night at No. 17 Coastal Carolina, which won in Lawrence each of the past two seasons. ... Baylor had two 100-yard rushers (Trestan Ebner and Abram Smith) in its season opener. ... Texas Tech's four interceptions against Houston were its most in a game since five against SMU in 2008. The Red Raiders had only five interceptions total in their 10 games last season.
