PHOENIX -- The Pac-12 may be going through a geographical shift in its pecking order.Oregon and Southern California, once the power centers of the conference, have dropped to the bottom. Washington and Colorado, typically near the cellar, have shifted toward the top.Its still too early to know if this movement is permanent; theres nearly two months until the Pac-12 Championship game in Santa Clara.Even if the changes arent for good, its sure made for an interesting season in the Pac-12 so far.A look at how the divisions stand heading into this weekends games:---NORTH DIVISIONOregon and Stanford have dominated the division and, for that matter, the conference. The Cardinal and Ducks have combined to win the last seven conference titles, including five times in the Pac-12 Championship game.This season, the Washington Huskies have been the top dog. The Huskies are 5-0 and lead the Pac-12 North after beating Arizona and Stanford to open conference play. They moved up to No. 5 in the AP poll this week, their highest ranking in more than a decade.Washington has a chance to end a long streak this weekend when it faces Oregon, a team thats beaten the Huskies 12 straight times.Were kind of burying our head in the sand, Huskies coach Chris Petersen said. I think they have done a good job of just paying attention to whats important and practicing hard and all those type of things.Stanford appeared to be the team to beat in the North after crushing Southern California and holding off UCLA. The Cardinal (3-1, 2-1 Pac-12) are still ranked No. 15 and certainly could make a run at the division title, but last weeks 44-6 loss to Washington was ugly.Oregon, once a perennial national-title contender, has fallen hard this season.After a pair of high-scoring wins to open the season, the Ducks (2-3, 0-2) have flailed the past three weeks, losing to Nebraska, Colorado and Washington State. The start has led to coach Mark Helfrich feeling heat from a fan base that had become accustomed to winning with Chip Kelly at the helm.We are built around people and culture and character and its in times like these you need them the most, Helfrich said. Not when the seas are calm and everything is great, its times like these.SOUTH DIVISIONUSC won the division a year ago and Colorado finished dead last after winning one conference game.The Trojans and Buffaloes have nearly swapped places this season, becoming two of college footballs biggest surprises.The Buffaloes were picked to finish last in the South again in the preseason poll and looked like they might be in for another long conference season after losing by 17 points to No. 4 Michigan.But then Colorado had coach Mike MacIntyre in tears after beating Oregon for its biggest win since joining the Pac-12 in 2011. The 21st-ranked Buffaloes followed that with a blowout victory over Oregon State to move into the AP poll for the first time since 2005.The Buffaloes (4-1, 2-0) lead the Pac-12 South by a game over No. 24 Utah and Arizona State, which travels to Boulder on Saturday.Like Ive said since Day 1, were a good football team, and I think every week weve gotten better, MacIntyre said. Every week.Utah has been a rising force in the Pac-12 the past couple of years, tying USC for second in the South last season after ending up fifth in 2014.The Utes (4-1, 1-1) have a dominating defense and opened the season with four straight wins before losing a close game to California last weekend. They host Arizona this Saturday and are still in position to win the division.USC was a popular pick to win the Pac-12, loaded with talented players on offense.Things did not pan out well for the Trojans early in the season. They were blown out by Alabama to open the season then lost to Stanford and Utah in consecutive weeks to fall to 1/3 for the first time since 2001.USC (2-3, 1-2) rallied with a rout over Arizona State last week, but still has a lot of ground to make up to repeat as Pac-12 South champion.

AIR FORCE ACADEMY, Colo. -- Receiver or running back -- Ronald Cleveland doesnt know how to classify himself.How about this: Burgeoning playmaker.Cleveland rushed for a score and caught a 62-yard TD pass as Air Force beat Abilene Christian 37-21 on Saturday for its 13th straight win at home.The sophomore plays a hybrid position in the Air Forces triple-option offense. His 33-yard TD run in the second quarter began a spurt of 21 straight points to help the Falcons (1-0) pull away from pesky Abilene Christian (0-1). Cleveland entered the game with one career carry.I dont want to be one of those guys if I come in the defense can key on me, said Cleveland, a football, basketball, track and soccer standout during his high school career in Franklin, Tennessee. I want to focus on getting stronger and being able to make those blocks you need to make on the linebackers and defensive ends. Do whatever I need to do.Hes certainly getting stronger. He can already bench about 60 pounds more than he could a season ago.Tremendous athlete. Highly skilled, Air Force coach Troy Calhoun said. The thing hes done -- finally has arms. When he first got here, this (microphone) cord right here was thicker than his arms. Hes added a little bit that way. It was good to see him contribute.Quarterback Nate Romine guided the offense in his return from a knee injury that sidelined him most of last season. He finished with two TD passes as Air Force improved to 21-0 all-time against Football Championship Subdivision teams.But he didnt play late in the fourth quarter, with backup Arion Worthman taking some snaps. Worthman threw a 17-yard TD pass to Jalen Robinette with 5:27 remaining.Asked if Romine was banged up, Calhoun simply responded: We chose to put Arion in there. We thought we needed to get him out there.Abilene Christian kept it close for most of the game thanks to a defense that recovered two early fumbles. Dallas Sealey threw three TD passes, including a 76-yard strike to Tracy James with 4:14 remaining that made it 37-21.We always say around our place, whenn you get squeezed the real you comes out, Wildcats coach Ken Collums said.dddddddddddd You saw the real us and I like what I see.Air Force hasnt lost at Falcon Stadium since Nov. 21, 2013, against UNLV. Its the longest home winning streak in team history.THE TAKEAWAYAbilene Christian: Dropped to 11-34 all-time against FBS teams, but proved they could hang with the bigger schools. It couldve been even closer, but James tripped over the turf after breaking into the clear in the second quarter and Brendan Conn missed a 35-yard field goal late in the third.These guys are a high-class outfit. They go to bowl games every single year, Collums said. They are tough, and they are relentless, and they are disciplined.Air Force: A ho-hum performance. The Falcons improve to 10-0 in season openers under Calhoun.REMEMBERING DEEThis was a difficult day for the Falcon family as they honored former quarterback Dee Dowis by wearing helmet decals that featured his initials and No. 6. The school also stenciled DD on the 6-yard-line at both ends of the field and held a moment of silence.Dowis died Monday morning in a car accident outside Atlanta. He was 48.A technician at running the option offense, Dowis graduated as the academys career leading rusher.Hed make plays on his own that were beyond sensational and yet the first thing -- and I dont know why this phrase sticks in my mind, but I heard it over and over and over -- `Hey, good job, yall, Calhoun recounted. That tells you a little bit in terms of how strongly he felt about the guys alongside him.UP NEXTAbilene Christian: Host Northern Colorado, Sept. 10. The Wildcats lead the series, 10-5-1, but have dropped five straight.Air Force: Host Georgia State, Sept. 10. The Falcons beat the Panthers 48-34 on Sept. 13, 2014, in the only meeting between the two teams.-----Follow Pat Graham on Twitter: www.twitter.com/pgraham34.
