Berk's Bests
Five facts, takeaways, opinions and hunches from Tuesday's conference call
1. Will Sutton is the talk of the Pac-12 Conference - at least as much as a defensive tackle can be the talk of a league. The ASU defensive tackle, the conference's reigning Defensive Player of the Week, has 10 tackles for a loss and 6 1/2 sacks this season. "He needs to go and start being paid. He's the best defensive lineman I've seen this year," Colorado coach Jon Embree said.
2. USC heads to Utah this week for the first time since 1917 - and Salt Lake City will be ready. "Having a marquee program like USC come to town is a huge deal and there's a lot of excitement that's been generated," Utah coach Kyle Whittingham said. The game is already sold out - the 15th straight sellout at Rice-Eccles Stadium.
3. Oregon coach Chip Kelly thinks his team plays all 60 minutes. He doesn't want to hear about being a first-half team or a second-half team. "The first three weeks, you all said we were a fast-starting team. Now, we're a second-half team. We play 60 minutes. It's an amusing phenomenon to us," Kelly said.
4. Arizona State has to stay healthy to keep winning. Sun Devils coach Todd Graham knows it: "We are very, very thin and that's a big issue with us." So far, ASU has stayed healthy and the result has been a 4-1 start and more and more attention each week.
5. Pac-12 coaches are split on tackling in practice. Arizona's Rich Rodriguez said his team doesn't practice tackling much during the week because of fear of injuries. On the other hand, Kelly said Oregon practices tackling three times a week and thinks his team is better for it. Oregon is ranked sixth in the league in total defense and Arizona is 10th.
Tweet of the day
Washington State coach Mike Leach didn't say anything too interesting Tuesday, so we interrupt "World According to Mike Leach" for the day's best tweet. It comes from Oregon senior offensive lineman Carson York tweeting to ESPN analyst Kirk Herbstreit:
"@KirkHerbstreit why do u get to have one of our new helmets in your office but as a UO player I can't have one when I'm done. Thanks #NCAA."
Dear Pundit
The Pac-12 Pundit will answer your questions all week long. You can usually track him down on Twitter at @patrickfinley, but hit up @dsberk this week and next if you have questions.
Dear Pundit, How many CDO graduates are going to be on the field this weekend at Palo Alto? - Ryan
A: That depends on Arizona safety Jared Tevis, who suffered an ankle injury against Oregon State. If Tevis plays, three former Dorados will be on the field: Tevis, Ka'Deem Carey and Stanford's Blake Martinez. And, for good measure, there will be a Sabino Sabercat on the field, too, in Keanu Nelson.
