The 40-year-old linebacker Junior Seau has officially signed with the New England Patriots after a few weeks of speculation that he would return to his former club.  Seau has stated he is not sure what his role will be, but that he trusts head coach Bill Belichick and he knows that the savvy coach has a plan for him.  I don’t know how effective Seau can be at 40 years-old, but the 12-time pro-bowler will at the very least provide some veteran leadership to a younger looking Patriots defense this year.  DL Terdell Sands was released to make room for Seau.
