Michael Adams caused a big chunk of Kansas City to catch its breath Friday night. Jamaal Charles, on his first carry since ACL surgery on his left knee last September, took a solid shot from the Arizona cornerback right where the scar is. But he jumped up and hustled back to the huddle, helping K.C. score touchdowns on its first two possessions en route to a 27-17 victory over the Cardinals in a very satisfying preseason opener.
