Inside the Raiders: Derek Carr winks to his critics as he aims to become Drew Brees 2.0 Sunday’s 33-8 loss to the Patriots in Mexico City told us everything we need to know about both.

No, the Raiders are not out of the playoff hunt just yet — that says more about the listless competition in the AFC than it does about Oakland — but Sunday’s loss to the Patriots showed us that this Raiders team doesn’t deserve to play in January, because it wasn’t even close to ready to play what was, effectively, a playoff game against a playoff team in November.

The Raiders had two weeks to prepare to play a neutral site game against one of the best teams in the NFL in a contest that was, for all intents and purposes, a must-win.

And they turned in their worst performance of a season full of poor performances.

How can this Raiders team say with a straight face that they think they can uphold their lofty preseason goals of making the postseason, winning in the postseason, and competing for a Super Bowl (lines they were happy to give out before Sunday) when they look so far from competitive against a perennial postseason participant?

They can’t. Which makes Sunday’s “home” loss in Estadio Azteca a defining moment for this Raiders team.

There are plenty of people to blame for Sunday’s debacle. You could point at the Raiders receivers for hosting a drop party. You can blame the Raiders’ porous defense for being a sieve. You can blame Derek Carr for — after a strong start — regressing into his back-foot-throwing, play-rushing, dink-and-dunking ways when the going got tough Sunday.

And, yes, all of those parties should be held accountable for Sunday’s loss and this lost season.

But Raiders coach Jack Del Rio deserves the blunt force of Raider nation’s scorn. If you haven’t already done so, subscribe to the Daily Dieter Podcast on iTunes. To view Dieter’s latest podcast on your mobile device click here.

Coaching is an ambiguous profession — how much of success or failure on the field is preparation and how much is having good players?

Sunday, there was little ambiguity. If there were votes of no confidence in football, Del Rio would be deserving of one Monday morning.

Yes, the Raiders defense didn’t have the personnel to match up with the Patriots offense on Sunday, but they were also given no schematic advantage that made going toe-to-toe with Brady and Co. possible.

The triumvirate that is the Raiders defensive coaching staff — led by the defensive-minded Del Rio, coordinated by the uninspiring Ken Norton Jr., and consulted by John Pagano (what else would you say he does for this team ?) — didn’t show any discernible adjustments or changes since the Raiders’ last contest against the hapless Dolphins. They ran out the same basic, uncreative, and unsuccessful defensive gameplan for Sunday’s game and expected different results.

There’s a term for that…

Brady, who had clearly seen every look the Raiders’ defense gave him a thousand times over in film study, was able to outwit the entire Raiders defensive coaching staff on the fly — changing plays at the line of scrimmage with the confidence that only comes from feeling impunity.

It was child’s play. Brady made such easy work of the Raiders’ defense that frankly, he looked bored by all the success he was having.

Could you have expected a different result from this Raiders defense? No. They’re arguably the worst unit in the NFL and Brady is arguably the best quarterback to ever play. Sunday’s performance was likely inevitable.

But you should have expected the Raiders defense to show different looks and different ideas — a gameplan that had ingenuity and complexity.

They should have made Brady at least have to think about it, maybe, if the wind blew just right, even work for it.

Instead, the Raiders coaches went to the tried-and-not-so-true: putting bad cornerbacks in deep zone coverage — as if giving Brady’s receivers more space was the way to slow him down — and praying that Khalil Mack would either break through his triple teams to create a one-man pass rush (he didn’t, though sometimes it took four) or that someone else on the Raiders defensive line would take advantage of the attention Mack drew (they didn’t).

It’s frankly insulting to Brady and Patriots coach Bill Belichick that Del Rio and Co. thought that would work.

And that’s just the defensive side of the Raiders’ problems.

The Raiders also had no inspiration, no composure, and no recourse after a first half from hell, Sunday. Bad halves happen. But the Raiders had a chance to make halftime adjustments and show that the first two quarters of Sunday’s game were an outlier — that this team was ready to rise to the occasion.

Del Rio’s halftime speech must have been a snoozer, because in a put-up-or-shut-up situation, the Raiders turned into mimes.

This Raiders team’s character was on full display Sunday, it takes after Del Rio’s.

In good times, Del Rio basks in the glory — happy to talk a big game about himself and his team, incredulous to the “doubters” and “haters” out there.

But then, in tough times, it’s finger pointing and copious of projection of insecurities.

Frankly, I’ve never seen a coach ride the emotional roller coaster the way Del Rio does.

His team follows suit, literally to a fault.

When the Raiders are playing well, they can pile it on with the best of them — they can look like juggernauts.

Take, for instance, the Raiders’ Week 2 win over the Jets — Oakland blew New York out, and the Silver & Black were dancing on the sideline in the second half. They rode the high as if it was never going to end.

But on Sunday, the Raiders lost their composure in the second half. Body language was terrible, complaining to referees was rampant, and Johnny Holton even punched a Patriot in front of an official.

They let their emotions get the best of them.

After the game, Del Rio showed us where his team learned that.

When asked about the team remaining focused for the rest of the season, Del Rio snapped back: “I don’t give credence to those kinds of questions.”

When asked about Mexico City, he complained that “if this was a road game, I’d enjoy it.”

No ownership, no culpability.

(Meanwhile, Carr was trying to take the blame for receivers dropping perfectly thrown balls. He might not be performing up to the standards of his new contract, but at least he’s willing to take some blame.)

Sunday’s game was so illuminating because no one can blame offensive coordinator Todd Downing for the loss. Fans can pin plenty of failures this season on the new guy’s lap, and Del Rio has done that in his passive-aggressive way, too, but then you also have to remember that Del Rio had no problem running Downing’s predecessor, Bill Musgrave, out of town at the end of last season. Despite what he’d like you to believe, Del Rio is hardly innocent in the Raiders offense’s year-to-year regression, too.

This is his team, his culture. The successes are his, and so are the failures.

And it’s clear now how this season will be defined.

As I’ve written time and time again, winning doesn’t create a culture, but cultures can create wins — and cultures are created by head coaches.

There’s no one on this Raiders team — from Mark Davis down to the practice squad players — who doesn’t deserve some blame for the Raiders’ disappointing 4-6 record, but on Sunday, the Raiders’ culture was fully exposed against the NFL’s gold standard.

It was an indictment of Del Rio.

And it raises the big question: While Del Rio deserves credit for taking Oakland from being a laughingstock to the playoffs, has he proven that he can take a good team and make it great?

I’d argue no, his lack of any division titles in his head coaching career argues no, and this season stands as further evidence that no, he doesn’t have what it takes lead a team to match or exceed expectations.

The Raiders have a ton of problems — it really has been a debacle of a year — but after Sunday, Del Rio, the man in charge, can no longer deflect the blame he deserves.
