Look for an in-depth review in the Weekend Wrap, which will be published Monday morning.

For now, five quick lessons …

1. The North rules the conference.

In six head-to-heads with the South the past two weeks, the North is 4-2.

But its superiority feels more substantial — it just looks like the better division, by far.

There are two elite teams in the North (Washington and Washington State) and at least two more upper-echelons (Stanford and Oregon).

The South has USC and …? Nobody else has proven a lick. Get Pac-12 Conference news in your inbox. Sign up for the Pac-12 Hotline newsletter.

UCLA beat Colorado, but the Buffaloes have shown nothing — and we saw what happened to both teams last week in head-to-heads against the North.

Utah remains a mystery, at least partly because of its schedule.

There’s no reason to think the Arizona school are top-tier.

From what I’ve seen thus far, only USC would finish in the top-four in the North.

Don’t be surprised if that winning percentage in inter-divisional games continues.

2. Bryce Love does not suck.

The Stanford tailback blitzed Arizona State for 301 yards and now has 1,088 through five games — reportedly the fourth-highest total to this point in the season in major college history.

Love is very much in the Heisman race and will remain there so long as he keeps producing and Stanford keeps winning. (The odds are piled high against him winning the trophy, as I outlined last week.)

His path become markedly more difficult next Saturday, when the Cardinal begins a stretch in which it faces Utah, Oregon, Washington State and Washington in a six-week span.

The astonishing production might not last, but for now, the year of the quarterback in the Pac-12 is on hold.

3. The grind has arrived.

It’s October, and the wear and tear is showing.

USC is battered, especially on the offensive line.

Utah, Stanford, Oregon State and Oregon have all been forced to play backup quarterbacks.

What’s more, everyone now has a stockpile of film to study. Tendencies have been exposed. Nothing is new anymore. The first-year head coaches and coordinators have lost the element of surprise.

The next month is all about adjustments and counter adjustments … about tweaks and creativity … about good fortunate and even better depth.

4. Washington is too good for its own good.

Hard to fault the Huskies for pounding all comers. The lopsided victories — they have won all five games by at least 16 points — are to their credit.

But they need a close game, and they need a close game before they’re in the close game they lose.

Best-case scenario: UW gets an unexpected scare in October (Cal, ASU, UCLA) and is forced to execute under pressure, thereby preparing Jake Browning and Co. for the inevitable make-or-break situation during their rugged November.

5. UCLA has not quit.

The Bruins sure looked like they had packed it in against Stanford, especially on defense.

But they showed well tonight against Colorado in a desperate situation and have, at least temporarily, blown away the dark clouds of dismissal hovering over Jim Mora’s office.

But goodness, they are a sloppy, unsound team. An illegal defensive substitution on third-and-two, coming out of a timeout? Yikes. Nine penalties? Typical. And add another ejection for targeting, this one absolutely justified.

Even when the Bruins win, they play poorly enough to lose. For more Pac-12 coverage
