ESPN is reporting that the New York Giants are interested in unrestricted free agents defensive end Jerry Hughes (Buffalo Bills), defensive end/linebacker Pernell McPhee (Baltimore Ravens), defensive end/linebacker Brandon Graham (Philadelphia Eagles), and defensive tackle Dan Williams (Arizona Cardinals).

The 26-year old Hughes (6’2”, 254 lbs) started 16 games in 2014 and finished with 53 tackles, 10 sacks, and three forced fumbles. The 26-year old McPhee (6’3” 280 lbs) did not start a game but was a key reserve for the Ravens, accruing 27 tackles, 7.5 sacks, and one force fumble. The 26-year old Graham (6’2”, 265 lbs) started one game for the Eagles, and finished the year with 47 tackles, 5.5 sacks, and four forced fumbles. The 27-year old Williams (6’2”, 327 lbs) started nine games, accruing 31 tackles and one sack. He is considered one of the better run-defending tackles in the game.

ESPN is also confirming the Giants interest in unrestricted free agent safeties Devin McCourty (New England Patriots), Rahim Moore (Denver Broncos), and Ron Parker (Kansas City Chiefs). However, ESPN says the cost for McCourty and Moore may be higher than what the Giants are able and willing to pay. On the other hand, NJ.com is reporting that the Giants are serious players for McCourty, who is expected to receive a contract worth $9-10 million per season. The Giants apparently reached out to McCourty on Saturday.

ESPN says the Giants are likely to re-sign linebacker Mark Herzlich, tight end Daniel Fells, and fullback Henry Hynoski, while safety Antrel Rolle, linebacker Jacquian Williams, and cornerback Walter Thurmond are unlikely to re-sign. NJ.com is reporting that safety Stevie Brown, Fells, and Hynoski are likely to be re-signed and that Herzlich and linebacker Spencer Paysinger may return.

Although teams cannot officially sign players from other teams until 4:00PM ET on March 10, the negotiating period began on March 7.
