ENGLEWOOD, Colo. — Von Miller has a message for Arizona, and it isn't exactly subtle.

"They're going to get our whole team's best, and that starts with me," Miller said Tuesday. "They're going to get my best this week, and we're going to go out there, and we're going to kick their ass. That's the way I'm feeling."

If Miller's promise comes true, it couldn't happen at a better time for the Broncos, who will aim to snap their four-game losing streak on "Thursday Night Football."

And with the level of conviction with which Miller spoke, it may not be wise to doubt him.

"We're going to kick their ass …" Miller said. "Make sure you put that up there [in a headline]: We're going to kick their ass. They're going to get our best this week. Last week was tough, the week before that, whatever.

"This week — Thursday night, prime time — they're going to get the Broncos' best."

Although the normally jovial Miller was largely serious on Tuesday, he said his proclamation wasn't a sign that he's irritated.

"I'm just confident," Miller said. "I'm confident in myself, I'm confident in my teammates — most importantly — and that's what we need. We'll be ready to go."

The distinction seemed subtle Tuesday as Miller deflected questions about Sunday's game vs. Los Angeles.

"That was last week," Miller said on several occasions.

Miller said he has turned his focus away from any issues that plagued the Broncos against the Rams or in previous weeks.

Instead, he's focused on leading his team to a win. And that could begin with a big play from him or rookie Bradley Chubb.

The two players combined for 4.5 sacks last week and have a combined 10 sacks through six weeks.

"If we're playing our best, I don't think there's anybody in the league that can block me and Bradley," Miller said. "We've just got to go out there and play. Especially not the Cardinals — they're going to get our best on Thursday. They've got to come with their best."

But if Miller's correct, even Arizona's best may not be good enough.

"We've just got to go out there and play Broncos football," Miller said. "If we play Broncos football, they won't be able to play with us. That's how I feel."

With "Thursday Night Football" just two days away, Broncos fans won't have to wait long to find out if he's right.
