Patriots signed RB Joseph Addai, formerly of the Colts.
Addai visited the Patriots last month, but otherwise received no other known interest on the free agent market. In New England, his primary responsibilities will be limited to third-down/passing situations. Stevan Ridley remains the leading candidate for early-down work, while 2011 second-round pick Shane Vereen and Danny Woodhead are complementary, change-of-pace options.
