Following the departure of Akiem Hicks, who signed with Chicago for a reported $5 million per year, defensive tackle remains one of the few holes on the New England Patriots' roster.
The Pats return two starters in second-year pro Malcom Brown and the 31-year-old Alan Branch. Dominique Easley also returns, but his durability is a concern. And there's Chris Jones, a former starter who missed the entire 2015 season due to injury.
Unquestionably, there is a need for another body along the interior.
In Terrance Knighton, the Patriots are targeting the biggest body available. Listed at 354 pounds, Knighton traveled to Foxborough Monday for a free agent visit, according to NFL Network's Ian Rapoport.
