The Browns and running back Peyton Hillis are still working on a new contract, but the bruiser insists the negotiations won't affect his play. "The bottom line is that it's not up to me in the end," Hillis said. "When people say they want to stop negotiating it's because they want to play better and they don't want the (salary) figure to hang over their heads. So for me, if they want to come back and talk, I'm open. "It's up to the Cleveland Browns and until that time happens, I'll continue to play my best." Browns general manager Tom Heckert declined to comment on the status of negotiations with Hillis, who is in the final year of his rookie contract. "Until we get a deal done with somebody, we're not gonna talk about it," Heckert said. Hillis, who rushed for 1,177 yards and 11 touchdowns last season, is scheduled to make a base salary of $600,000 this season.
