The AFC North side will be using their opening pre-season clash against the St Louis Rams to test some of their less experienced players.
The head coach told the team's website: "That's the big thing. Going from the practice field to going to the games. The lights are on, there are more people in the stadium, and the fans are there. So, seeing their reactions and how guys handle that is a big part of this.
"Not just from knowing the scheme and the ability of doing it against someone else. Guys get used to seeing what they're seeing from the guys they are going against. Now is a chance to see how they react to guys that they haven't seen a lot of.
"I think, overall as a team, I'm looking to see guys competing out there to win, seeing what they carry over from the practice field, and their execution and their efficiency to the game, ultimately the kind of effort and establishing the identity that we want to establish."
The Browns finished last season last in their division with five wins and 11 losses.
