There’s a gigantic, first-time conference showdown inside the Big Ten between Ohio State and Oregon taking place in Week 7, so ESPN had to bring College GameDay to Eugene on Saturday afternoon.

Both teams are undefeated, so the showdown will have giant College Football Playoff implications. Outside of Autzen Stadium, other clashes like the Red River Rivalry between Texas and Oklahoma, as well as Penn State traveling to the West Coast to face USC will adorn screens throughout America.

Before all the action takes place, the College GameDay crew made their selections for Week 7’s slate. Joining the desk as the Celebrity Guest Picker was none other than Kaitlin Olson of It’s Always Sunny in Philadelphia fame, who was born in Portland in 1975, and is an Oregon graduate from 1997. Check out all of their picks below.

ESPN College GameDay Picks for Week 7:

Ohio State at Oregon: Herbstreit and Saban are on the Buckeyes, while Howard, McAfee and Olson are on the Ducks to get the job done in Autzen Stadium on Saturday evening.

Red River Rivalry — Texas vs. Oklahoma: Kirk Herbstreit is calling the game so he’s not picking, but the rest of the crew had to make their selections known. Everyone is on the Longhorns though.

Kansas State at Colorado: Coach Prime made an appearance on College GameDay, would that help the Buffaloes’ case? The Wildcats are favored, but the whole crew is on Colorado.

Ole Miss at LSU: Olson dropped a Joey Freshwater reference while picking the Rebels, and Saban and McAfee agree, but Howard and Herbstreit are on the Tigers.

Penn State at USC: Nobody is a believer in the Trojans on the College GameDay set.

Florida at Tennessee: The whole crew is on the Volunteers on Saturday.

California at Pittsburgh: Olson and Herbstreit believe in the Golden Bears over the Panthers.

Arizona at BYU: Olson is the lone dissenter, riding with the Wildcats in Week 7.

Iowa State at West Virginia: Howard, Saban and Herbstreit are on the Cyclones, while Olson and McAfee are on the Mountaineers.

Washington at Iowa: Another interesting Big Ten clash for the Huskies. They weren’t very popular in Eugene, or on the desk, as everyone is on the Hawkeyes.
