QB Case Keenum on the Broncos' offensive struggles against the 49ers:

"We didn't play well. We didn't play well really at all. You got to give those guys credit. They came out and played extremely hard. We quit playing. We got, for whatever reason, we put ourselves in tough situations on third down and didn't convert things down the field, didn't help our defense out and it's tough. We've got to help our defense out. We've got to keep them off the field. We've got to do better than going three-and-out. We've got to do better. We've got to stay on the field. We have to score points and we didn't do that at all the first half especially."

LB Von Miller on the Broncos' defensive struggles:

"I don't know. We just relaxed I guess. We didn't come out swinging in the second half. We just, I don't know. We just aren't playing. The San Francisco 49ers, they're a talented team. They played well today. They beat us today. For me personally, three false starts in the first half is just flat out ridiculous. I'm a gambling man and I broke today. I broke today. I put my team in a horrible situation, very undisciplined and guessing around, but in the end it ended up hurting us and that's on me."

Miller on what he saw out of Kittle:

"Eighty-five is a hell of a player. George Kittle's a hell of a player and he took some 10-yard plays the distance today. There's not too many tight ends in the league that can do that. We knew coming into the game that he was going to be talented. We knew coming into the game he was going to make plays, but the plays that he made today he just killed us on top of the penalties, and on top of my penalties that increased the situation. He just killed us."
