The Patriots announced the signing 19 rookie free agents Friday, including another defensive back from Rutgers. After drafting Rutgers cornerback Logan Ryan and safety Duron Harmon (as well as linebacker Steve Beauharnais) last week, the Pats inked Scarlet Knights cornerback Brandon Jones to compete for a spot in a secondary that already includes Rutgers alumnus Devin McCourty. Jones, who stands 6-foot-1, recorded a team-high five interceptions last season and was a standout special teams player. Other undrafted players signed by the Pats are: punter Ryan Allen (Louisiana Tech), fullback Ben Bartholomew (Tennessee), defensive lineman Dewayne Cherrington (Mississippi State), safety Kanorris Davis (Troy), offensive lineman Elvis Fisher (Missouri), tight end Brandon Ford (Clemson), defensive lineman Cory Grissom (South Florida), running back Quentin Hines (Akron), offensive lineman Josh Kline (Kent State), offensive lineman Chris McDonald (Michigan State), wide receiver T.J. Moe (Missouri), cornerback Stephon Morris (Penn State), linebacker Ian Sluss (Portland State), offensive lineman Matt Stankiewitch (Penn State), tight end Zach Sudfeld (Nevada), wide receiver Kenbrell Thompkins (Cincinnati), defensive lineman Joe Vellano (Maryland) and long snapper Mike Zupancic (Eastern Michigan).
