The unbeaten and fourth-ranked Washington Huskies are enjoying their best ranking since the end of the 2000 season, but they are heading into what their coach calls their toughest test of the season.

Washington (7-0, 4-0 Pac-12) plays at 17th-ranked Utah (7-1, 4-1) on Saturday afternoon, and Rice-Eccles Stadium will be rocking, further fueled by the energy of having ESPN's "College GameDay" program on campus.

"Rice-Eccles has been a great venue this year," said Utah coach Kyle Whittingham, whose team is tied atop the Pac-12 South with Colorado. "We have had great support from our fans that makes it a tough place to play for opponents. We need that to be the case this weekend, and we know they will be loud."

Washington is coming off its 10th consecutive victory, a 41-17 win over Oregon State at Husky Stadium last week. The Huskies have defeated every opponent this season by at least 24 points, except for an overtime victory at Arizona.

Washington has the top-rated defense in the Pac-12 (14.6 points allowed per game), leads the country with in turnover margin (plus-2.0 per game), has the nation's No. 2-rated passer (Jake Browning, 199.6 efficiency rating) and the top rusher in the conference (Myles Gaskin, 103.9 yards per game).

The Huskies have outscored their opponents 200-24 in the first half.

"This will by far be our toughest test so far," Washington coach Chris Petersen said of Utah.
