Week 5 is here with some huge Pac-12 matchups. Here’s what to watch:
No. 10 Washington vs. No. 7 Stanford, 6 p.m., ESPN/WatchESPN
Keep your eyes on both defensive lines in this game. Both teams have been successful in getting pressure on quarterbacks without a blitz. Nine of Stanford’s 10 sacks have come on standard pressures while all 13 of the Huskies’ sacks have come when bringing four or fewer players. This is especially important because if the Cardinal can get good pressure on Jake Browning, they have a good shot at a win. Washington is 10-1 when Browning is sacked three or fewer times, but it is 1-4 when he’s sacked four or more times. History says: Stanford has won the past three meetings between these two and seven of the past eight, and Stanford has never lost a Friday night game as a ranked opponent. But, a Washington win would give the Huskies their first 5-0 start since 1992.
Colorado vs. Oregon State, 11:30 a.m., Pac-12 Networks
The Buffs are coming off a huge upset win over Oregon on the road and looking for their fourth win of the season, which would match their win total from a season ago. And yes, that fourth win last season came against the Beavers as well. Oregon State is looking for its second win of the year, which would match its win total from a season ago. The Colorado defense will look to extend its fantastic defensive play into its matchup with Oregon State. The Buffs are holding opposing quarterbacks to just a 52 percent completion percentage and have given up just eight completions of 20-plus yards (both of which are second-best in the Pac-12).
Cal vs. No. 18 Utah, 3 p.m., Pac-12 Networks
Utah is looking for its second consecutive 5-0 start, which hasn’t happened in back-to-back seasons in Salt Lake City since 1929-30 (those two teams went on to have 7-0 and 8-0 seasons). If the Utes win this game, it would give Kyle Whittingham his 100th win, which would put him in the company of Ike Armstrong, who coached the 1929 and 1930 seasons and is the only other Utah coach to have won 100 games. Meanwhile, Cal is looking for its second consecutive win against an AP Top-25 opponent this season, which hasn’t happened for the Bears since the 2009 season. Cal snapped its 11-game losing streak to Top-25 opponents when it beat then-No. 11 Texas.
USC vs. Arizona State, 5:30 p.m., FOX
The Sun Devils have already given up 26 plays of 20-plus yards and 22 of those were pass plays, so Sam Darnold, in his second career start, will have an opportunity to hit on some big pass plays. Against Utah, Darnold completed five passes of 20-plus yards and completed 69.2 percent of his passes. Arizona State’s Kalen Ballage will be the player to watch on the other side of the ball. The junior averages 6.4 yards per rush, and thanks to a seven-TD performance against Texas Tech he’s second in the FBS with nine rushing touchdowns. USC’s run defense has struggled this season, giving up 4.7 yards per rush (10th in the Pac-12) and 17 rushes of 10 or more yards (eighth in the Pac-12).
Washington State vs. Oregon, 6:30 p.m., Pac-12 Networks
For the first time since the 2007 season, Oregon has lost two in a row (during that 2007 season the Ducks ended up losing three in a row -- Arizona, UCLA and Oregon State). This could be a penalty-riddled game if these two teams’ tracts hold up. Oregon and Washington State are two of the top four most-heavily-penalized teams in FBS. The Ducks are averaging 97.3 penalty yards per game while the Cougs are just behind them at 96 yards per game.
UCLA vs. Arizona, 7:30 p.m., ESPN/WatchESPN
UCLA quarterback Josh Rosen will be facing the Arizona defense that sacked Washington QB Jake Browning four times last weekend. The Wildcats have blitzed on 34 percent of opponent drop-backs this season, up from 21 percent in the 2015 season. Rosen has faced the blitz quite a bit this season, on 28 percent of his drop-backs to be exact. On those possessions he has completed 64 percent of his passes and been sacked three times. If the Wildcats want a chance at their first conference win, they’re going to have to get after Rosen.
