There are many ways to measure defensive lines: Sacks, tackles, rushing yards against. Usually it's not a financial yardstick. The Bills may be an exception.

"I think two guys on the D-line are $100-million guys, so they're expected to play well and they have played well," Giants offensive lineman Justin Pugh said of Buffalo's wealthy and wily duo of Mario Williams and Marcel Darius.

This week it is up to the Giants to make sure the Bills' defensive front doesn't bother their own $100-million investment, Eli Manning. It will be a difficult task against a team that has led the NFL in sacks the past two years.

"Every single guy on that defensive starting front would be the best player on another line, you know what I mean?" Pugh said. "You have Pro Bowlers all the way across the board, so we've got to go out there and it's going to be a great competition for us."

The possible return of starting left tackle Ereck Flowers from an ankle injury should help. Flowers was limited Wednesday but seems to be on track to play Sunday.

Business as usual?

Tom Coughlin saw the free-agency workout of former first-round pick Hakeem Nicks on Tuesday as business as usual in the NFL.

"This is the time of the year to evaluate, to keep your lists in order, to know how you would go if you need it," he said. "It's pretty much standard to try and work whatever group you possibly can, at least on a weekly basis at this time of the year. There is nothing unusual about that."

Of course that was before Victor Cruz's setback early in Wednesday's practice.

Giant steps

The Bills will likely be without RB LeSean McCoy (hamstring) on Sunday . . . Rookie DE Owa Odighizuwa (foot) could see his first game action this week. "Another powerful kid that can rush the passer," Coughlin said of the possible addition to the rotation . . . CB Dominique Rodgers-Cromartie, who missed last week's game with a concussion, was a full participant yesterday.
