The Rams have agreed to terms with center Jason Brown on a five-year deal worth $37.5 million. Of that amount, $20 million is reportedly guaranteed to Brown, who played with the Ravens last season. "We stressed even during the season about getting bigger on the offensive line, more physical, and he fits everything," general manager Billy Devaney said Friday. "(Jason's) smart, big, young, and of strong character. "The arrow's still going up on him ? an ascending player. So there's a lot of good traits about him. And Butler ? the same thing. He's in the prime of his career."
