Chicago Bears middle linebacker Brian Urlacher understands that time is running out on his career.
He realizes the sense of urgency that faces his team and the questions that have resulted from the Bears' recent run of mediocrity. He also accepts that there are no guarantees of how much longer he'll be with the franchise.
"I'd like to think I could play as long as I wanted," Urlacher said. "But I also know that there aren't many players who get to make that call."
