These six rivalries are being built the old-fashioned way — on the field. And there’s no contrived, committee-designed trophies, no quaint nicknames that hark back to a more innocent time, and definitely no corporate sponsorship.:

•

Southern California-Oregon: This one is up and running as one of the best new rivalries of the new century. The Ducks have traditionally saved the long knives for Oregon State and Washington, their unfriendly neighbors to the north. But in recent years, Trojans-Ducks has been the conference’s premier rivalry. The Nov. 3 meeting in Los Angeles might be a preview of the Pac-12 title game this season.•

Wisconsin-Ohio State: Ohio State will always save its hate for That School Up North. But the Wolverines haven’t seriously been in the hunt for the conference title since 2006, when Ohio State won a classic No. 1 vs. No. 2 game. You know who has been? The Badgers. This season, they play Nov. 17 in Madison.•

LSU-Alabama: This might be the only rivalry game in which you can lose to the other and still win the national title. There’s no reason to think the Nov. 3 matchup in Baton Rouge hasn’t been circled on calendars all over Louisiana and Alabama.•

TCU-Baylor: This is one to keep an eye on. Now that TCU is in the Big 12, and Baylor has shown signs it can stay competitive in the league, the annual Horned Frogs-Bears meetings could gain some real traction. They get together Oct. 13 in Waco.Cincinnati-UConn: Cincinnati has rather quietly won the Big East title in three of the last four years, and gotten the league’s BCS bid twice before being shunted to the Liberty Bowl last season. They finish this season up against each other, too, on Dec. 1 in East Hartford, Conn.

Extra point: Keep an eye on West Virginia-Oklahoma State. This could become a must-watch game every year.
