Keenum's goal to hold the ball and move down the field will not be without challenges. The Chiefs rank 29th in the league in points allowed, but they've allowed their opponents to convert just 25.8 percent of their third-down attempts. That's the best mark in the league, and it's a big reason the Chiefs are 3-0.

"Obviously, they're scoring a lot of points," Keenum said. "Statistically, they're giving up yards, but man, they're doing really well on third down. They're getting teams in third-and-long. Obviously, they can rush the passer. They've got some guys that can get after the quarterback. And they're solid in the back end. They've got some veteran guys that have played a lot back there. They give you a lot of different looks.

"I'm excited to get out there on Monday night. We've got a really, really good challenge for us."

After watching Keenum during the first three weeks, Joseph said he has reason to believe the Broncos' quarterback will continue to improve. That could bode well for the Broncos' chances to convert third downs and score points against the Chiefs.

"Case is getting better and better each week," Joseph said. "Week 1 — outside of the turnovers — he made some plays for us, same with Week 2. Week 3, we ran the ball, made some plays. It was really penalties that pushed us out of scoring range. We could've scored 20 more points last week. If we do that, everything changes. I've been really pleased with how Case has played. He's going to play better and better for us."

Keenum seemed to agree with the final line of Joseph's assessment, which allowed for room for the seventh-year quarterback to continue to grow in his first year with the Broncos.

"At times, I'm where I want to be, but at times I'm not," Keenum said. "I guess you could say, overall, I'm still a long way from where I want to be. I feel like this offense can be really, really, really good, and at times we are. At times, we're moving, we're rolling, and other times, for whatever reason, we're getting off the field. Just keep building. We're going to keep building this house, we've built a great foundation."
