Browns quarterback Jason Campbell wouldn't say he's coming in to try to beat out Brandon Weeden for the starting job, but said, "I definitely think I can still play at a high level.''

Speaking on a conference call today, Campbell said he'll play whatever role the Browns and coach Rob Chudzinski want him to, even if it's just as a mentor to Weeden and the others.

“First, Coach hasn’t said anything or promised anything,” said Campbell, who signed a two-year deal worth $3.75 million on Tuesday. "We’ll work to try to improve our football team. Whatever my role is, I’m going to give 100 percent in it. I’m going to help along the way.”

Campbell said he knows that Weeden a was a first-round pick and "I'm definitely willing to help him. There are some things I can help him with and talk to him about.''

Campbell said it "was real tough'' to go down with a broken collarbone courtesy of the Browns in 2011 when he was off to a 4-2 start in Oakland.

"I felt like I was coming into my prime,'' he said. "It was my third year in that offensive system.I felt I was really taking off, really blossoming.”

He said it's largely the same system the Browns are running here now. He ran it in Washington under Al Saunders and in Oakland under Hue Jackson.

He added, "The team that broke my collarbone is the team I'm playing for now. How ironic is that?''

He added that he's excited to come to a young team and try to help out, and that he's looking forward to working for Chudzinski and Norv Turner.
