Carter, a 10-year veteran of San Francisco and Washington, put up double-digit sacks in both 2007 and 2009, but like Albert Haynesworth was unhappy with the switch to a 3-4 defense.
While Bill Belichick was quick to dismiss the focus on a 4-3 or 3-4 as a "media fabrication", the Patriots have certainly been adding the sort of personnel that could easily work in a 4-3. This is just the latest in a series of defensive line pick-ups that began with Albert Haynesworth, and comes just 12 hours after the Patriots added ex-Jets DE Shaun Ellis.
