Things we learned from Sunday's game:
The linebacker sacked Brock Osweiler five times, including one for a safety, and the Raiders snapped an eight-game losing streak against their AFC West foes with a 15-12 victory.
Still, there was plenty of blame to go around, starting with Denver's leaky line,Cheap Stitched Jerseys, which only produced 34 yards on the ground and allowed Mack to blow through for five sacks in the second half.
"I believe it's the quarterback's job, no matter how the day is going, to get his team in the end zone," Osweiler said. "I didn't do that today. I'll figure out a way to fix it and we'll move forward."
Or throw to those slippery fingered receivers.
The Broncos saw their already fickle quarterback situation thrown into more flux Sunday, courtesy of a suddenly revitalized rival in Oakland and a very good pass rusher in Mack.
Osweiler's receivers weren't much better. Of the quarterback's 16 incompletions, at least a half-dozen were drops. One, by Demaryius Thomas, cost Denver a touchdown late in the first half. Thomas also lost a fumble. Another drop, by Vernon Davis, came on fourth-and-5 with less than 4 minutes left and nullified what would've been a 20-plus-yard gain.
Manning, nursing an ailing left foot, is back to throwing. Asked if the five-time MVP would participate in practice this week, coach Gary Kubiak said Manning is "moving forward" with his rehab but "I don't want to get too far ahead of myself."
"He should get better this week," Kubiak said of Anderson.
Oakland took care of the Broncos despite gaining only 126 yards, and though the loss could hardly be blamed on Manning's replacement, the easiest place to check for changes in Denver over the next few weeks will be under center.
Manning went 22 for 35 for 266 yards and two interceptions in the first game. Osweiler was 35 for 51 for 308 yards and no picks on Sunday.
THE MACK ATTACK: Mack's five sacks were the most in the NFL since 2012, when Aldon Smith had 5.5 for the 49ers. And they were the most by a Raider since Howie Long went for five against the Redskins in 1983 — the regular-season game that preceded their Super Bowl matchup.
CJ SITS: Broncos running back C,Wholesale China Jerseys Free Shpping.J. Anderson hurt his ankle last week. He was suited up but Kubiak said Anderson was available only in case of emergency. Apparently starter Ronnie Hillman's stat line — 12 rushes for 20 yards — wasn't considered emergency material.
"Still confident and great in the huddle,NFL Jerseys Cheap," Broncos tight end Owen Daniels said of Osweiler. "We have to play better around him."
Osweiler led the Broncos inside the Oakland 20 three times in the first half but they didn't score a touchdown and settled for a 12-0 lead. Oakland (6-7) outscored the Broncos 15-0 in the second half. The Broncos haven't scored a touchdown in seven quarters.
NO END ZONE: The Raiders finished the season without allowing Denver an offensive touchdown. Denver's only TD was Chris Harris' interception return in a 16-10 win in Oakland in Week 5.
DENVER (AP) — Even if he is ready, it's hard to think Peyton Manning would want to step in behind that offensive line.
"I wasn't making the right reads at times. I wasn't making the right throw at times. It culminated in a loss tonight," he said.
It might help that he won't have to worry about Khalil Mack, though.
Del Rio explained that long snapper Jon Condo had hurt his right shoulder while recovering Sanders' fumbled punt. The backup snapper, Lee Smith, had an injured wrist and Del Rio said Smith had a cast on his snap hand. So, given the options, Del Rio thought there was a better chance of making the 2-pointer.
GOING FOR 2: Del Rio chose to go for 2 after a touchdown put the Raiders ahead 15-12 early in the fourth quarter because both his long snappers were injured. Carr threw incomplete, and instead of needing a touchdown, the Broncos only needed a field goal to tie.
"A big-time mood swing," Sanders called it. "I'll put this entire game on my back."
Osweiler took responsibility.
Also,Wholesale Baseball Jerseys China, Oakland's go-ahead touchdown was set up by a muffed punt by Emmanuel Sanders at the Denver 11.
"When that's the case,wholesale jerseys china, you have to use the information and have the courage to do the right thing for the team," Del Rio said.

Now, instead of controlling their destiny for best record in the AFC, the Broncos (10-3) are a game behind New England, which beat Houston 27-6.
