Broncos outside linebacker Von Miller has never started a season without a sack in his first two games.

But after he and the rest of the defense were blanked Monday night against Oakland, it is imperative Miller and Bradley Chubb pressure Chicago quarterback Mitch Trubisky on Sunday to give the Broncos a chance to win.

“If I don’t get a sack and then we lose on top of that, it’s a double loss for me,” Miller said. “That’s my job and I like to get my job done.”

But it’s not all on Miller and Chubb to get sacks. They need third-and-longs to feast so the run defense and coverage must improve from what happened Monday.

The Raiders were 10 of 14 on third down, including 5 of 6 when needing three or fewer yards to convert. That limits the impact of Miller and Chubb, who must be aware on the edge of defending the run on third-and-short instead of going full-steam ahead toward the quarterback.

“We have to do a better job of stopping the run and breaking up some of those quick passes so it becomes second-and-10 and maybe third-and-7-plus,” coach Vic Fangio said. “And then the pass rush will have a chance. I’m not saying that our pass rush would have been great last week, but we really don’t know because it didn’t have much of a chance.”

Raiders quarterback Derek Carr threw quickly, but that’s a fact of life against premier pass rushers. Carr was 10-of-12 passing for 68 yards when he threw in less than two seconds. On 16 attempts, he threw in less than 2.50 seconds.

According to The Denver Post’s game charting, Chubb had 18 pass rushes and dropped into coverage four times and Miller had 20 rushes and four coverage drops.

Chubb batted down a pass, which, if the Bears use the quick passing game, Fangio wants to see more awareness from his rushers.

“We have to try and get our hands up and bat some of those (down),” Fangio said.

Said defensive coordinator Ed Donatell: “When there are quick throws, you have to get on people tighter and mix your coverages a little bit and tackle great. There can be no leaky tackles because that turns into shorter third downs.”

Fangio was complimentary of Miller’s play against the run, which is admirable, but No. 58’s primary job is to pressure the quarterback and he knows it.

“We’ve got a great defense, we have a lot of great players and we’ve got a great pass rush,” Miller said. “The game before has nothing to do with this game that we’re about to play.”
