This is kind of old, but I’ll throw it out there nonetheless. The Patriots are looking at another 2 potentially large impact free agents.
The first is Chris Brown, ex-Titans runningback. Brown is large, at 6-3 and 220 lbs and is plenty powerful. He was the Titans starting back between 04 and 05 and ran for more than 1000 yards and 6 touchdowns in 2004, while missing 5 games. He was put on the bench last year, but is still a productive runner at age 26. He would be a good fit next to Maroney.
The other guy was ex-Bears defensive tackle, Ian Scott. Scott was big, and a good fit for the 3-4, however, he signed with the Eagles one day after visiting the Patriots. Scott was the first free agent to visit and not sign a contract.
The Patriots were also still looking at linebacker Edgerton Hartwell, however he signed with the Bengals on May 3rd.
