Ted Miller Taking stock of the fourth week of games in the Pac-12. Team of the week: Washington State. While the Cougars buddies in Seattle deserve a tip of the cap for winning at Utah, it's not an exaggeration to say Washington State's comeback, 31-27*victory at Colorado was the most important*result of the Paul Wulff Era. It was a show of mental toughness that will be nearly as important as improved talent for the Cougs return to relevance. Best game: The Cougars came back from a 10-point fourth-quarter deficit with two TDs in the final 2 1/2 minutes, then forced a fumble to clinch the win. The key play was a 63-yard TD pass from Marshall Lobbestael to Marquess Wilson with 1:10 remaining. Biggest play: Well, in order to spread the wealth -- Lobbestael-Wilson duly noted above -- Arizona State running back Cameron Marshall, playing on a*nagging sprained ankle, turned in a physical,*multi-tackle breaking 37-yard TD run against Oregon State that put the Sun Devils up 28-20 in the third quarter of a surprising tight contest with Oregon State. Most memorable play: New category here to commemorate Stanford QB Andrew Luck's unbelievable, one-handed 13-yard reception against UCLA that also included him athletically getting a foot in-bounds. Hey, if the QB thing doesn't work out, there's always tight end (and we're only half-joking; he could play tight end). Offensive standout: There will many outstanding offensive performances, but USC quarterback Matt Barkley completed 32-of-39 passes for a school-record 468 yards with four touchdowns in the Trojans' 48-41 victory over Arizona. Defensive standout: Washington State LB Alex Hoffman-Ellis had 14 tackles -- 12 solo -- and two sacks against Colorado. Special teams standout:*Jamal Miles,*Arizona State's*multi-purpose star had a 78-yard punt return for a touchdown in the*win over Oregon State, which Smiley face: The state of Washington. As Bud Withers of the Seattle Times pointed out, Washington and Washington State won road conference games on the same day for the first time since Oct. 18, 2003. Might the Apple Cup have some real stakes for both teams this year? Frowny face: The new Pac-12 members. Colorado and Utah are now a combined 0-3 in conference play and 3-6 overall. The Buffaloes blew a 10-point fourth-quarter lead against Washington State, and Utah may have lost QB Jordan Wynn for a few weeks with a shoulder injury. Thought of the week: Pac-12 defenses need to pick it up. No conference team ranks in the top-25 in total defense -- Stanford and California are 26th and 27th, respectively -- and eight rank 50th or worse. Here's a guess that the teams playing for the Pac-12 title on Dec. 2 will have top-50 defenses. Questions for the week: Does Arizona State (4-1, 2-0) sew up the South Division on Saturday at Utah? The Utes, widely viewed as the Sun Devils top competition for the division title when the season began, are 0-2 in conference play and likely won't have Wynn. USC isn't eligible due to NCAA sanctions, and Arizona, UCLA and Colorado haven't shown much thus far. Originally posted by ESPN.com - Pac-10 Blog Click here to view the article.
