Former Bills defender Aaron Schobel says he's going to retire. Buffalo released Schobel on Aug. 4 after nine seasons and he initially indicated that he planned on continuing his career. "I really didn't have a lot of fun playing last year," Schobel said. "The passion wasn't there, so it was time. I took as much time as I felt like I needed to make the decision, and I think I made the right one."
