The New Orleans Saints are adding more reinforcements to their group of defensive linemen. Veteran Kendall Langford tweeted on Wednesday night that he had signed with the Saints. The 31-year-old Langford spent the past two years with the Indianapolis Colts. He was a third-round pick by the Miami Dolphins in 2008, and after four years with Miami, he spent three years with the Rams before going to Indianapolis. Although he's played defensive end for much of his career, the 6-foot-6, 305-pound Langford might be a better fit at defensive tackle. The Saints have struggled to create much interior pressure thus far this season.
