A college football rivalry never exactly cools off, at least among the emotionally involved. But rivalries do go through upticks and downticks of relevance, both regionally and nationally.
So which Pac-12 rivalries are heating up, stagnating or cooling as we head into the 2014 season?
The facts: USC leads the series 46-30-7 and has won 12 of the last 15 games, but the Bruins have won two in a row under Jim Mora, including a 35-14 domination last year.
The meter: Sizzling and rising.
The animosity between the fan bases is always strong, but what makes a rivalry truly heat up is relevance. And substantial stakes. This rivalry is gaining in both areas. USC is one of the preeminent football programs in the nation, even though UCLA fans hate to read that. UCLA is the rising western power under Mora, even though USC fans mock the idea. USC has a new coach in Steve Sarkisian and is moving past NCAA sanctions. UCLA is a top-10 team eyeballing the College Football Playoff. Know what I say? Release the hounds!
The facts: Arizona leads the series 47-39-1, but Todd Graham has won the last two against Rich Rodriguez, including a 58-21 blowout last year in Tempe. Before that, the visiting team has won eight of the last 13 matchups, including the last four -- games that were decided by a total of 15 points.
The meter: Blistering and heating up.
While Oregon-Washington fans provide the most blowback to the Pac-12 blog -- Yakety Yak! Oh, yeah! Yakety Yak -- Arizona and Arizona State fans are a strong No. 2. It used to be the fans hated each other and whined a lot -- "You cover them more... waaaaaa!" -- because both teams were fairly mediocre. But the Sun Devils won the South Division last year and are now 2-0 under Todd Graham against the Wildcats and Rich Rodriguez. With both programs trending up in an overall sense, the rivalry is gaining relevance. It also helps that Graham and Rodriguez don't particularly care for each other.
The facts: Washington leads the series 58-43-5, but the Ducks have won 10 straight in the series by at least 17 points, including a 45-24 win in Seattle last year.
The meter: Hot but stagnating.
This has long been the most bitter Pac-10/12 rivalry but it has experienced a dramatic power shift to the Ducks. Sorry Huskies, you know it's true. It seems like Oregon fans these days are more worried about winning that darn absent national title than fretting about that team from up North. Now, if Washington and new coach Chris Petersen go into Autzen Stadium and steal one this year... well, that can't happen. Can it? Maybe that possibility needs to be debated.
The facts: USC has won nine of the last 12 meetings, but the Fighting Irish has won three of the last four, including a 14-10 win last year. Since 1967, USC has gone 24-20-3 in the series.
The meter: Simmering with many hoping for a boil (particularly TV executives)
As far as national rivalries go, this one is without peer. It's an annual classic that matches two of college football's top powers. Lately, both teams have been nationally relevant, albeit not on an annual basis, and that's the issue. This rivalry is more about national relevance than bitterness. What it needs to heat up is for both teams to be national contenders with the winner in line for the College Football Playoff.
Washington-Washington State Cougars
The facts: Washington leads the series 68-32-6, including a 27-17 victory last year. The Cougars have lost 11 of the last 16 Apple Cups, but are 1-1 under Mike Leach.
The meter: Simmering with lots of potential spice
Have you stopped and pondered just how fun this one might get if Petersen and Mike Leach get their programs' performances to match their respective coaching reputations? For one, in terms of the media, it could be a Don James-Jim Walden deal where Petersen is a "2,000-word underdog" to the loquacious Leach. As it is at present, the Cougars really, really hate the entitled Huskies but the Huskies reserve their most bitter distain for Oregon.
The facts: Oregon leads the series 61-46-10 and has won the last six meetings, including a 36-35 thriller in Autzen Stadium last year.
The meter: Warm but in need of another log on the fire
Know what bothers Oregon State fans? When some Ducks fans say they root for the Beavers when the two aren't playing. It probably isn't a statement of emotional fact, but Oregon fans recognize it as the ultimate patronizing gesture. See above with Washington: The Beavers really, really hate the entitled Ducks but the Ducks reserve their most bitter distain for Washington. Now, if the Ducks start to slide a bit and the Beavers push past them in the North Division -- or at least become Oregon's equal again -- this one will immediately boil over, potentially returning to the back-and-forth turf battle it was from 1998-2008, when it was one of the conference's most interesting and meaningful rivalries.
The facts: In a series that dates back to 1905, USC holds a 59-29-3 lead, but Stanford has won four of the last five meetings. Still, a year after Stanford upset the then-No. 2 Trojans, USC returned the favor by knocking off No. 4 Stanford 20-17 last fall.
The meter: Most rivalries are more about the fans than the players. This one might be more about the players than the fans. These two teams go at each other -- hard. Things really picked up steam with former Stanford coach Jim Harbaugh mouthing off about Pete Carroll, then backing it up with two wins, including the classic "What's your deal?" game in 2009. Stanford started USC's and Lane Kiffin's downward spiral in 2012, while the Trojans ended the Cardinal's national title hopes in 2013. And I personally enjoy watching the Stanford band drive the Coliseum crowd crazy -- "And now a tribute to a great USC graduate... Joe Francis!"
California Golden Bears-Stanford
The facts: Stanford leads the Big Game rivalry 54-44-10 and has won four in a row, including a 63-13 blowout last year.
The meter: Luke warm until Cal rights itself
The Big Game is a great rivalry with a great history. The problem is getting the two teams to be good at the same time. Cal dominated the rivalry under Jeff Tedford until 2009. Now the Cardinal is fully in control. Second-years Bears coach Sonny Dykes probably could win over the Old Blues by pulling the upset this fall, but that will mean winning as a double-digit underdog.
BYU Cougars-Utah Utes
The facts: Utah leads the series 57-34-4. Utah has won four straight and nine of the last 12 games with the Cougars, including a 20-13 victory last year in Provo.
The meter: Always hot but chilling for two years
Utah has dominated this bitter series of late, most notably since joining the Pac-12, but there will be a two-year hiatus until the Holy War is renewed in 2016. That is unfortunate, as the series hasn't been interrupted since BYU didn't field teams during World War II (1943-45). Further, BYU is presently outside looking in, as it is not a Power Five conference member. It will be interesting to see how things go in the future.
The facts: Colorado leads the series 31-26-3, and this is both teams’ longest series against any Pac-12 team. They played annually from 1903-62 with four exceptions, but then the rivalry went dormant for 49 years before it resumed in 2011 as Pac-12 members. As Pac-12 members, Utah leads 2-1 having won two in a row.
The meter: Tepid while awaiting some seasoning
Sure, this is a bit of an artificial rivalry. They are paired as rivals because they joined the conference together. But as both start to develop their Pac-12 legs, you can count on this rivalry heating up. They will be compared for a long time. Neither wants to be the one not measuring up. And don't forget the "Red Bike Incident."
