Raiders head coach Jack Del Rio came into Sunday's game facing a tough, but familiar foe in Kansas City Chiefs head coach Andy Reid.
Reid has always been tough to go up against after a bye week, holding a 15-2 career record after a week off coming into Sunday's game. That tally improved on Sunday as the Chiefs came into a wet Oakland to defeat the Raiders 26-10, handing them their second loss of the season.
It certainly wasn't the kind of day the Raiders were looking for when a win would've helped take control of the division.
"Not the kind of afternoon we were hoping for today," Del Rio said after the loss. "We took our lumps. We were out-played and outcoached."
Del Rio's defensive players echoed his sentiment, while also emphasizing that the players need to correct the mental mistakes.
"Biggest issue is the attention to detail," cornerback David Amerson said. "It is not the guys going out there and getting out physical or beat on every play. It is the little details and the offense doing things that messes with our eyes and us not being in the right spots on the plays."
The season is now six weeks old, leaving 10 weeks to get it right.
"I think we have made corrections," Amerson said after Sunday's loss. "All it takes is that one play where something can happen and the play goes for 70 yards. It is based on one play, whether it is in the passing or the running game... you got to be fundamentally sound and detailed, and just do better at that."
Del Rio knows the defensive woes must be fixed if his team is going to end its playoff drought.
"It can't continue," Del Rio said. "Not for us to be the kind of team we had designs on being. We're sitting here at 4-2 right now. Coming off a day that didn't go the way that it needed to go for us to go home with a big smile on our face. We'll get ready for the next opportunity."
Despite being out-gained in all six weeks of 2016 so far, the Raiders defensive players aren't losing confidence that they can get it corrected.
"I mean it's frustrating," linebacker Bruce Irvin said. "I still believe in this group. We feel like we got a great group of guys. We are going to continue to work and turn this thing around.
