Tom Coughlin's Jacksonville Jaguars downed Bill Parcells' New York Jets, 16-6, tonight. It was the first time Coughlin, who was an assistant under Parcells with the Giants and credits the current Jets coach with boosting his career, defeated his mentor in four NFL tries, including two playoff games.

The Jaguars, whose vastly upgraded defense has allowed just 52 points, never let New York (1-4) get going. Not that Jacksonville (4-1) did much offensively, either.

It didn't matter with the way Tony Brackens, Carnell Lake and the Jaguars' defenders were performing. Not even an eight-minute delay to repair a tear in the artificial turf -- which is in its final year at Giants Stadium -- bothered them.

For the third time this season, the Jaguars, who had four sacks, held an opponent without a touchdown. Jacksonville appears to have a playoff-caliber defense to go with what normally is a high-powered -- but lately has been a sputtering -- attack. In all, the Jets gained 226 yards, 51 coming on a last, desperation drive.

Mike Hollis kicked three field goals and James Stewart had a three-yard scoring run for all the Jacksonville points. John Hall made two field goals for New York.

Jacksonville showed no signs of its recent offensive struggles on its first possession, marching 61 yards on 13 plays to Stewart's scoring run. Stewart, playing for injured starter Fred Taylor (hamstring) was involved in eight of the plays on the drive.

Then, the punters took center stage. Tom Tupa sent a 54-yarder that was downed on the Jacksonville 1. So Bryan Barker returned the favor with a team record 83-yarder.

The Jets reached Jacksonville territory on two straight series, but their inability to adequately protect quarterback Rick Mirer kept stymying drives. When Mirer's pass to Quinn Early deflected off the receiver's hands and then off teammate Keyshawn Johnson's to safety Blaine McElmurry for his first NFL interception, the Jaguars took over at their 46.

A 33-yard completion to Keenan McCardell on which he turned around cornerback Aaron Glenn set up Hollis's 32-yard field goal for a 10-0 lead.

But the Jets responded thanks to a 43-yard kickoff return to midfield by Dwight Stone. Mirer got enough time to find Johnson for 16 yards before the drive stalled and Hall made a 33-yard field goal.

Hollis's 44-yarder, set up by Brunell's 31-yard pass to Reggie Barlow, opened the second half. Hall hit from 42 with 8 minutes 53 seconds left. Hollis capped the scoring with a 21-yard field goal with 1:46 to play.
