New England safety Rodney Harrison wouldn't officially close the door on his playing career, but he sounds as though he's leaning towards retirement. "Right now, I'm doing a lot better, and I can't honestly say if I'm going to play or not right now," said Harrison. "I'm up in the air. Right now, I'm focusing on being able to run up and down the bases with my son, so once that's established, then I'll decide if I want to play or not." Harrison, 36, will soon become a free agent.
