Looking for the best places (outside of The Huddle, of course) to get updates on free agent signings and NFL news?   Here are the websites that I recommend checking regularly to keep up on what's happening:   OFFICIAL TEAM PAGES      Team Website - http://www.panthers.com/ Team Twitter - https://twitter.com/Panthers      TEAM NEWS PAGES    The Charlotte Observer - http://www.charlotteobserver.com/sports/nfl/carolina-panthers/ Black and Blue Review - http://blackandbluereview.com/ ES
