On getting geared up for a struggling 49ers team:

"The phrase any given Sunday is a cliché for a reason. Just look the scores. The Bills going into Minnesota and doing what they did, there's examples every week. We don't feel we're anywhere near being on top of where we should be. If you truly study the film, from the last couple of weeks, without Garoppolo in there, they've done a nice job offensively. They've turned the ball over. That's been the issue. But you don't put up 30 first downs by accident against an NFL defense. We have our hands full. The tape doesn't lie. They dominated the game, it just didn't show up on the scoreboard."

On the defense's progress:

"We feel good about where we're headed, but there's a lot of details we need to get cleaned up. There's no substitute for game reps. There's no easing into this. There's no honeymoon period. We're in the win-now business, and our guys realize that. We've got a long way to go until we feel like we're a truly cohesive unit, where guys know what the guy next to them is doing, where there's the trust. It's only natural not to have that in the beginning. I like where we're headed, but there's always that urgency to get where we want to go quicker."
