The AFC North side's three-game winning streak came to an end with their 31-17 loss to the Detroit Lions last Sunday.
The head coach told reporters: "I feel like we had a good week of preparation. The focus and energy was really outstanding from the guys on the team, who hold themselves to a high standard, and that's the thing that's impressive.
"It says a lot about this team to me, where they're at, the identity that we're establishing. We have a relentless group of guys that are tough. They stick together and are passionate about playing football.
"You could see [quarterback Brandon Weeden] specifically working to improve in areas that we're talking about that he needs to improve. I'm expecting him, and have confidence in him like the team does, to go out and play his very best."
The Browns are currently third in their division.
