Giants DT Damon Harrison was part of a Giants team last season that made the playoffs for the first time in five seasons, but he says many players in the locker room believe there is room for improvement heading into this season.
"We've got a bunch of guys who aren't comfortable with what they've done last year," he said on Thursday. "Whether it be [defensive tackle] Robert Thomas, or [safety] Landon Collins. Nobody is happy, or satisfied, or content - whichever word you want to use - with what they've done last year. Last year doesn't matter anymore."
Harrison can tell how driven the players are when he notices the work they do to prepare for the season -- away from the public eye.
"When nobody's watching, when the camera's not here, when the coach is not watching," he said. "I was here with [defensive tackle] Jay Bromley. I've seen Robert Thomas working, I've seen Landon working. And that right there, that's all you need to know about a guy - how hard he works when the cameras aren't there."
Harrison said he is prepared for Sunday night's season opener against the Dallas Cowboys, noting that he's been "going up against the New York Giants all offseason - or I think since April.
The Giants defeated the Cowboys twice last season, but RB Ezekiel Elliott was able to find success against the Giants' run defense. He ran for 107 yards when the two teams faced each other for the second time in December.
"We have to do our job first and we did a pretty good job of corralling him in the second game - just a lot of leaky orders," he said. "Guys just trying to do too much."
Harrison had 86 tackles, 2.5 sacks, and five stuffs in his first season with the Giants. He played his first four seasons with the Jets after going undrafted in the 2012 NFL Draft.
