The Jacksonville Jaguars suddenly have a big-play offense to accompany their smothering defense. It was the defense that most embarrassed Kansas City in a 17-7 win Sunday. Maurice Jones-Drew sped 52 yards for Jacksonville's first touchdown and the Jaguars held the Chiefs to a shocking 10 yards rushing. Only Brodie Croyle's 13-yard touchdown pass to Samie Parker on the final play enabled the Chiefs to avoid their first shutout at home since 1994. The Jaguars (3-1), who gave up 282 yards rushing to Tennessee in losing their season opener, have not allowed more than 48 yards on the ground in any of three games since, all wins.
