This has nothing to do with the 49ers, but I am simply amazed by this story. According to 790 The Ticket in Miami, Chad Johnson filed the necessary paperwork to legally change his last name from Johnson to Ocho Cinco. That link is to ProFootballTalk.com, which has been known to post some sketchy rumors. However, it's also been mentioned at ESPN and The Sporting News.
Personally, I get a kick out of Chad Johnson's (or Ocho Cinco I suppose) antics, primarily because they're not something the 49ers have to handle. There were stories of big time locker room tension, which is definitely not something you want if you're trying to win football games.
However, it sounds like things calmed down in the past couple months, so we'll see if he behaves himself. In the meantime, just enjoy this highest of comedy.
