The Peyton Manning touchdown passes kept coming an NFL-record seven in all for the Broncos in a 49-27 nationally televised rout of the Ravens in the NFL opener on Sept. 5 and the reactions of those watching ranged from awe from fans to fear from upcoming Denver opponents.

The Giants defensive players who were watching the game felt neither awe nor fear knowing they would be facing Manning and the Broncos in Sunday’s home opener at MetLife Stadium.

They saw opportunity.

“What was it like watching it on TV? I loved it’’ cornerback Antrel Rolle said Thursday. “I love going up against the best of the best. It only allows me to go out there and test myself and see where I am as a defender and to test our entire defense. [Manning] is going to give us everything.

“But his game is not about Peyton. It’s about us as a defense.’’

The Giants defense was not exactly dominant against the Cowboys in a 36-31 loss but one must be careful judging that unit considering the fact the offense turned the ball over a ridiculous six times putting the defense in unmanageable positions for most of the night.

“This is a big match-up for us at home start of our home season and we don’t want to be 0-2” cornerback Terrell Thomas said. “I’m excited. Everybody is claiming them to be whatever they are — Peyton Manning and seven touchdowns. What better for us than if we go out there and shut them down?’’

Thomas who likely will spend much of his day covering Wes Welker in the slot knows the outcome of Sunday’s game will have everything to do with how the Giants’ defense handles Manning and his band of prolific receivers.

“They have a great offense but we’re looking to be a great defense’’ Thomas said “so this is a perfect challenge for us.’’

Both Thomas and Rolle insisted they relish the chance to play the cat-and-mouse head game at the line of scrimmage that Manning plays changing calls or calling out fake ones to try to confuse the defense.
