COLUMBUS, Ohio (AP) - Neither Purdue's Danny Hope nor Ohio State's Urban Meyer can trust their defenses these days.

As a result, no one has any idea what's going to happen when the teams meet on Saturday at Ohio Stadium.

The Boilermakers (3-3, 0-2 Big Ten) have been dinged for an average of 41 points and 527 yards in losses the past two weeks to Michigan and Wisconsin, both at home. Over that same span, the Buckeyes (7-0, 3-0) have escaped with wins over Nebraska and Indiana while surrendering 43.5 points and 458 yards a game.

After a week of being openly doubted, neither defense is feeling very good about itself.

The big question now is, will they respond to the criticism or are their underlying problems that can't be easily solved?
