The Patriots' dramatic split in effectiveness running to the left side as opposed to the right side has a bit to do with injuries and a bit to do with talent. Most of New England's running plays go behind left tackle Matt Light and left guard Logan Mankins, but the performance on the right side has deteriorated since 2004. While Nick Kazcur is penciled in as the starting right tackle, he's been pretty average so far in his career, while injury replacement Ryan O'Callaghan is a project that wasn't ready when he entered the starting lineup last year. O'Callaghan will be pushed by former Alabama tackle Wesley Britt, who looked better than either O'Callaghan or Kazcur in his one start against the Bengals last year. Right guard Stephen Neal missed time with a shoulder injury, and took a step back from his 2005 form.
