Jason Williams and Sean Lee will get the first shot at replacing Bobby Carpenter as the Cowboys’ nickel linebacker.
The youngsters’ roles could be much bigger than that, though, with 34-year-old Keith Brooking coming off knee surgery. Williams, a 2009 third-round pick, didn’t earn defensive snaps in his first season. Lee, whom Dallas had 14th overall on its 2010 draft board, is likely more NFL-ready than Williams right now even though the former Penn State Nittany Lion is a rookie.
