Raised stakes and contempt bred by familiarity. Conference play is different, and at this point it becomes the focus of the college football season.
The Big 12 starts Saturday with a showdown in Oklahoma, as the sixth-ranked Sooners face No. 15 Kansas State. In the Atlantic Coast Conference, No. 4 Florida State and No. 10 Clemson will go a long way toward deciding a division title in Tallahassee, Fla.
The Sooners and Wildcats bring contrasting offensive styles to Norman. Oklahoma plays up-tempo and tends to air it out with quarterback Landry Jones. K-State’s star quarterback Collin Klein is battering ram who leads a deliberate, run-first attack.
Last year, the Wildcats were 7-0 when Oklahoma came to Manhattan, and the Sooners turned what was billed as a big game into a laugher. Jones passed for a school-record 505 yards in a 58-17 victory, in which the Sooners outscored the Wildcats 35-0 in the second half.
Kansas State’s pass defense is shaky again, ranking at the bottom of the Big 12. The Wildcats’ best defense might be Klein and tailback John Hubert churning out yards on the ground and keeping Jones on the bench.
Oklahoma head coach Bob Stoops is 7-1 against his former boss, Kansas State’s Bill Snyder.
In Tallahassee, the Seminoles are coming off a 52-0 victory against Wake Forest that looked about as easy as the Savannah State game the weekend before. They’ll be looking for a little payback against the Tigers.
Clemson beat the ‘Noles 35-30 last season and went on to win the Atlantic Division, and eventually the ACC title.
Clemson’s ability to keep Florida State’s talented defensive ends Bjoern Werner and Cornellius Carradine away from quarterback Tajh Boyd will be key.
Lots can happen, but it’d be a big surprise if the winner Saturday night in Doak Campbell Stadium wasn’t playing in the ACC title game.
In the Pac-12, the marquee game is in Eugene, Ore., and it’s for fans of fast-break football. Rich Rodriguez, one of the godfathers of the fast-pace spread offense craze, against Chip Kelly, who has revved up the spread to warp speed with the Ducks.
No. 3 Oregon has been unchallenged through three games, with D’Anthony Thomas racking up big plays. No. 22 Arizona is off to an encouraging start with Rodriguez, but the Wildcats will get a better idea of where they stand Saturday night.
