ALAMEDA — You bet the Raiders could win Sunday.

Not that I would actually bet the Silver and Black farm on them beating the 49ers. But I don’t rule it out, even if the Raiders are something like eight-touchdown underdogs (all right, actually an eight-point underdog).

In fact, I can do even better. I can lay out exactly how the Raiders can accomplish the upset at O.co Coliseum.

Here is my 12-step plan for them to follow — 12 steps because that matches the jersey number of Rich Gannon, the last Raiders quarterback to defeat the 49ers, during the 2000 season:

1. When the pregame torch is fired up, have Ronnie Lott or Jerry Rice light it.

Ever since Al Davis’ death, the Raiders have preceded home games by having a former player or coach flip the switch on the commemorative flame that honors the late team owner. So what if this Sunday, the former Raiders player is also one of the 49ers’ former greatest players? That’d be throwing down the gauntlet, get the crowd even more amped up and have at least a few 49ers players going: “Huh?” Would Lott or Rice even agree to this, before a 49ers game? Ask. My gut tells me they might.

2. Show up and play as if you’re running to a party with free beer, not as if buses are running in the parking lot.

Last Sunday’s flatness in the 52-0 loss at St. Louis was inexcusable. The Raiders must reclaim the energy they possessed in the Thursday night home game against Kansas City two weeks ago. Fortunately, the O.co Coliseum crowd should be off the hook and assist that passion upgrade. But please, Raiders and 49ers fans alike, keep the enthusiasm nonviolent. After all, you purchased that $100 game ticket to watch professional athletes slam into each other, not to get beat up yourself for no compensation and then fork over more dough for bail money. I never understand that mindset.

3. If you win the coin toss, defer and play defense first.

Have you seen the 49ers offense lately? Quarterback Colin Kaepernick may be answering questions with few syllables. He’s making even fewer first downs. Put the 49ers on the spot right away to show their team weakness isn’t.

4. Force the 49ers to only throw the ball.

Thursday, Raiders coach Tony Sparano said that his team had to “eliminate one phase from” the 49ers offense. Sparano would not specify which phase he wanted the Raiders to squash, which is understandable. Why give away the game plan? But the strong guess here is that the Raiders will try to stop the run and put the ball in Kaepernick’s hands, because for all their problems, the Raiders have the league’s ninth best pass defense. The problem: They are 27th against the run. Hey, I didn’t say this would be easy. But with the 49ers’ offensive line injuries and depth issues, the Raiders are facing them at the right time.

5. On offense, hand the ball to Latavius Murray.

He’s the second-year running back who exploded for that 90-yard touchdown run against the Chiefs as if he’d been shot out of a circus cannon. Murray then suffered a concussion and was forced to miss last week’s ugliness in St. Louis. Sparano indicated Thursday that Murray will be back at full go against the 49ers but wasn’t certain how the running back rotation would unfurl. Then Sparano added: “I have a pretty good idea.” Hmmmm, wonder what that idea could be?

6. Put an alarm buzzer in the helmet of quarterback Derek Carr.

The Raiders’ talented rookie quarterback is performing the way rookies often do, making some stellar plays that show great promise but also making errors — forcing the ball into coverage or throwing late down the middle — that you can see coming a few seconds in advance. Solution: Give offensive coordinator Greg Olson a buzzer linked up to Carr’s helmet earhole so that when Olson sees disaster looming, he can push a button that signals Carr: “Take a sack or throw the ball out of bounds!” It could prevent a key turnover. What? This is illegal under NFL rules? Who says you have to tell anyone?

7. Hand the ball to Latavius Murray.

Why not? Murray has got such fresh legs, with just 14 carries this season. (For comparison purposes, the 49ers’ Frank Gore has 181.)

8. Embrace the punt.

I envision this as a slog-across-wet-turf kind of game with one of those 9-7 or 10-6 final scores. So if the Raiders defense is playing well, Carr should feel OK about not taking chances on third down, allowing punter Marquette King to handle fourth down. In the midst of last week’s debacle, King still managed to hold the Rams to just 19 total return yards. Keeping the 49ers offense pinned back puts more pressure on it to produce.

9. Hand the ball to Latavius Murray.

Did I already mention this?

10. Leave it to SeaBass.

If the Raiders defense can keep it close deep into the fourth quarter, the result can come down to a field goal. Sebastian Janikowski has not had a game-winning kick in the final minute or in overtime since 2012. He’s overdue.

11. Hand the ball to Latavius Murray.

I think you get the idea.

12. Make sure Sio Moore and Khalil Mack understand that sacking Kaepernick in the waning seconds does not require a backfield celebration as festive as a Christmas pageant.

Guys, trust me: A victory handshake is far more satisfying. And if you help win this one, I can guarantee you’ll be asked to return one day and light the torch.
