The two schools moved in opposite directions, though.
The Cougars jumped four spots to No. 21 in the AP poll and from unranked to No. 25 in the coaches poll after opening the season with a 50-21 victory over South Florida.
The Utes, meanwhile, dropped six spots to No. 13 in the AP poll and seven spots to No. 15 in the coaches poll after losing 29-26 to Florida.
The Gators entered both polls after beating Utah, coming in at No. 12 in the AP poll and No. 19 in the coaches poll.
Utah State also received five votes in the coaches poll, after losing 55-0 to top-ranked Alabama. The Aggies, who started their season with a win over UConn, received 12 votes in the coaches preseason poll. USU did not receive any votes in this week’s AP poll.
Up next for BYU is Baylor, which jumped to No. 9 in the AP and No. 8 in the coaches after a 69-10 win over Albany. The Cougars will host the Bears this Saturday at 8:15 p.m. MDT at LaVell Edwards Stadium.
The last time BYU hosted a Top 10 team while also ranked itself was in 2009: that year, the No. 16 Cougars hosted No. 10 TCU and lost, 38-7.
Two other BYU opponents this season, Notre Dame and Arkansas, also were on the move after facing ranked opponents in Week 1.
The Fighting Irish dropped to No. 8 in the AP poll and No. 9 in the coaches poll after losing 21-10 to Ohio State, while the Razorbacks are No. 16 in the AP and No. 17 in the coaches after beating Cincinnati 31-24.
There was significant movement for the Pac-12 as well.
Oregon lost 49-3 to defending national champion Georgia, and the Ducks dropped out of the AP poll and to No. 24 in the coaches poll. The Bulldogs, meanwhile, are now No. 2 in both polls.
BYU plays Oregon on Sept. 24, while Utah faces the Ducks on Nov. 19.
That leaves USC, a 66-14 winner over Rice, as the Pac-12’s only other ranked team besides Utah in both polls. The Trojans, who play at Utah on Oct. 15, jumped four spots to No. 10 in the AP, and moved up three spots to No. 13 in the coaches.
