Story line: Gunther Cunningham, the workaholic first-year coach of the Chiefs, is conservative by nature. So is his game plan. “Their whole mentality is to play good defense, not turn the ball over, run the ball and when you get tired of that, run the ball some more,” Raven Coach Brian Billick said. “It’s a sound philosophy.” Billick used plenty of aerial weaponry last year as offensive coordinator of the Minnesota Vikings. But in an effort to make things easy for inexperienced quarterback Stoney Case, he has employed a low-risk attack that would make Cunningham proud.
