Raiders veterans James Jones and Justin Tuck have been on the wrong side of a blowout before, so the 52-0 defeat at the hands of the St. Louis Rams isn’t something that they aren’t sure how to overcome.

The fact the Raiders play the 49ers on Sunday at the Coliseum makes it even easier for the Raiders to purge from their memory the shellacking by the Rams and gear up for their Bay Area rivals.

“The best thing for us now is to turn all of our attention and our focus to what lies ahead, and that’s this bloodbath that we’re about to have against the 49ers,” Tuck said. “Big rivalry game. Everybody in this area has been waiting for this game for a long time.

“That’s the best thing that could have happened after a loss like that, is to have this type of game where all of your attention has to be focused on the 49ers.”

Raiders coach Tony Sparano made sure that his players and coaches moved past the Rams as soon as possible.

In fact, Sparano said the way he deals with a loss like the one the Raiders endured Sunday is no different than the way he handled things after his team’s victory over the Chiefs on Nov. 20.

“Move on quickly,” Sparano said. “Move on just like you do every game. We’ve been in this position before. Our guys have bounced back. They have handled it well. We’ll continue to do so.”

By early afternoon Monday, Sparano and his players had watched video of the Rams game, made the necessary corrections and shifted their focus toward the 49ers. Sparano said the players were excited by the time they left the facility.

“When you come off a game like (Sunday), to know that you have that opportunity this week, in your stadium, with your fans out there, it certainly gets the players excited.”

Tuck and Jones said the Raiders don’t stand a chance against the 49ers or, for that matter, any other team if they commit the kind of mental mistakes and fundamental errors that occurred against the Rams.

Both were at a loss to explain how the Raiders went from an upset of the Chiefs to a face plant against the Rams, especially when the Raiders had three extra days’ rest. The breakdowns came at every turn, with no player or coach immune from criticism.

“Mental errors showed up a lot from every position,” Jones said, “and that’s unacceptable, especially this late in a season and you’re still having the mental errors that we had on basic plays. You’re not going to win ball games like that.”

The Raiders got dominated from the outset, in every phase of the game. The Rams scored touchdowns on their first five possessions and cruised to the easy win.

Sparano counted 19 missed tackles by his defense. He also pointed out just how costly one fundamental error can be.

On one play, the Rams got stuffed for a 1-yard gain on a run similar to the one that yielded an 89-yard touchdown by Tre Mason in the second quarter, Sparano said.

Same play, same running back, just a matter of the Raiders defenders being in the proper spot.

Jones said the Raiders are talented enough to beat any team in the league. It’s simply a matter of everyone doing his job at a high level on a consistent basis.

Offensively, the Raiders failed to get into a rhythm against the Rams, as has been the case in most games this season. The Raiders didn’t net a first down on their first three drives, while the Rams surged to a 21-0 lead.

“Once this offense is in rhythm, we’re really hard to stop,” Jones said. “But once you get us out of rhythm and we’re going three-and-out and we’re not establishing a groove, we’re not that good.”

Against the Rams, the Raiders were about as bad as they have been at any point in recent memory. They were so bad that it might have been beneficial, in a strange way, Tuck said.

“Losses like this are a lot easier to get over than those ones that come down to the last drive of a game,” Tuck said. “Obviously, it’s very embarrassing to be a part of something like that but that drives you to kind of just have a short memory and throw it out the window.”

— Rookie George Atkinson III fumbled two kick returns against the Rams, and he also committed a penalty on a punt return.

Sparano said Atkinson’s play was indicative of a young player making his first appearance in an NFL regular-season game and wanting to make an immediate impact.

“When the game went the way it went, I felt like a lot of guys were pressing, trying to make a play,” Sparano said, “and that’s natural. You’re a young guy out there, you want to try to make an impression in that situation. The problem is, you’ve got to use good judgment.”

Sparano said he is confident that Atkinson III will learn from his inauspicious debut and be a productive player for the Raiders in the future.

Atkinson signed with the Raiders as an undrafted free agent out of Notre Dame. He spent the first 12 weeks of the season on the practice squad before he was signed to the 53-man roster Saturday.

— Sparano still is awaiting word on the severity of the injuries suffered by right offensive tackle Menelik Watson (ankle) and tight end Brian Leonhardt (concussion) against the Rams.

For Leonhardt, that marks his second concussion in two games, which makes his availability even more in doubt for the 49ers game, if not the rest of the season.

— Rookie left guard Gabe Jackson entered the game when Watson got injured Sunday, and he played 54 of 81 snaps.

Sparano said he intended to get Jackson some work anyway in Jackson’s first game back since he hurt his left knee against the Seahawks on Nov. 2.

Jackson was a “little sore” Monday and his uneven play reflected the fact he had missed three games, Sparano said.

— Running back Latavius Murray is “close” in his return from a concussion, Sparano said, “but we’re not there yet.”

Murray missed most of the Chiefs game after he endured a helmet-to-helmet hit by Chiefs safety Kurt Coleman and all of the Rams game.

Murray practiced on a limited basis two days last week, but he got shut down Friday after he failed the final test in the league-mandated concussion protocol.
