                === Eagles add five, including Chung, Casey ===
 Philadelphia,  PA  (Sports Network) -  The Philadelphia Eagles brought in five
 new players during Tuesday's opening of free agency, including three potential
 starters  to  a revamped  defense in safety  Patrick Chung, cornerback Bradley
 Fletcher and nose tackle Isaac Sopoaga.
 The  Eagles also  added  former  Houston fullback/tight  end  James Casey  and
 linebacker Jason Phillips in an active first day.
 Chung  comes  to Philadelphia  after a  four-year tenure  with the New England
 Patriots  in which  he often battled injuries, having missed 12 games over the
 past  two  seasons. A second-round  pick in  the 2009 draft, the 25-year-old's
 best  campaign  came in 2010, when  he amassed 96 tackles, three interceptions
 and nine passes defensed.
 The Oregon product is also familiar with new Eagles head coach Chip Kelly, who
 was the Ducks' offensive coordinator during Chung's final two college seasons.
 Fletcher played his first four NFL seasons with St. Louis and started 15 games
 for the Rams in 2010, registering 75 tackles, four interceptions and 11 passes
 defensed. He served as that team's primarily nickel back last year and came up
 with 28 stops, one interception and one sack.
 Both  Chung and  Fletcher should have an opportunity to start in an overhauled
 Philadelphia  secondary that allowed a league-high 33 touchdown passes in 2012
 and  parted  ways  with  high-priced cornerback  Nnamdi  Asomugha  earlier  on
 Sopoaga, who made 71 starts for San Francisco over the past five seasons, will
 likely  be the  regular nose tackle in Philadelphia's new 3-4 scheme. The 330-
 pound  run  stuffer had spent  his entire nine-year  career with the 49ers and
 produced 27 tackles and one sack for the NFC champions last season.
 The versatile Casey posted career highs of 34 catches, 330 receiving yards and
 three  touchdowns for  the  AFC South  champion Texans  last  season, and  has
 compiled 66 receptions totaling 752 yards over his four years in the NFL.
 Phillips had 22 tackles and made two starts for Carolina this past season. The
 27-year-old  broke into  the league as a fifth-round draft choice of Baltimore
 in 2010.
