Coughlin: Who better than the champs to practice against?

Tom Coughlin came to New England to learn from the Patriots, not to rub their noses in the two championships he won from them. The Jacksonville Jaguars executive vice president has been roaming the practice fields at Gillette Stadium, where they are working out with the Patriots in the days before their exhibition season opener on Thursday night. ''Obviously, they're the world champions,'' Coughlin said after practice Tuesday.
