How much can Trent Edwards hurt Bills?

The Buffalo Bills are wary of the information quarterback Trent Edwards has divulged to the Jacksonville Jaguars.

"They'll ask," Bills coach Chan Gailey said, "and he'll tell."

EdwardsEdwardsEdwards has Gailey's playbook committed to memory after six months of skull sessions, practices, four preseason exhibitions and two regular-season games as Buffalo's starter.

The Bills waived Edwards last week. The Jaguars claimed him, and he's coming back to Ralph Wilson Stadium to play his old team Sunday.

Edwards won't start for Jacksonville. The job belongs to David Garrard, but the Jaguars thought enough of Edwards to cut their other quarterback, Todd Bouman, this week. Edwards is the only backup.

"We'll have to change some signals and some thought processes," Gailey said, "We'll have to adjust some things. That's all a part of it when a guy from one team goes to another team. That's what happens."

When NFL schedules were finalized, Week 5 was viewed as one of Buffalo's more winnable games. But Jacksonville is 2-2 and coming off a rousing final-second victory over the Indianapolis Colts.

It won't help the Bills' cause that Edwards has inside information on them.

The intel Edwards can share isn't trifling. Edwards can recognize formations and audible calls. He has been privy to strategy talk on how the Bills want to attack in certain situations. He can tell Jacksonville defensive coaches where the Bills are weakest in pass protection.

"He'll have viable information to give them," Bills receiver Lee Evans said. "That's just how it is sometimes. It happens across the board."

As an example, Evans mentioned Bills backup quarterback Brian Brohm's familiarity with the Green Bay Packers as being beneficial to the Bills in Week 2. The difference, however, is that Brohm hadn't been with the Packers since last November, when he was on the practice squad.

Gailey named Edwards his starting quarterback, and as recently as last week Edwards had access to practically every diagram of offensive game strategy the Bills had drawn up since Gailey arrived. He poured over game film.

"He can have an impact," Bills running back Fred Jackson said of Edwards. "We do have some different things there. So hopefully we can kind of counteract that. He was in the system. He knows what's going on, but at the same time they still have to stop it."
