At Giants training camp, the only thing to disturb the silence has been the screaming of the boisterous new defensive coordinator, Perry Fewell. There have been no public contract disputes. No will-he-or-won't-he retirement sagas. No serious injuries -- not yet, at least. Forget making a splash. So far, the Giants have not made much of a ripple, and that is the way they like it. Under the Mara family's leadership, the Giants have never equated showiness with success. Coach Tom Coughlin said the distraction-free training camp was not a product of a single person or any off-season addition, but an indication of a collective vision. 'That's a reflection of our team, and our team's commitment and their focus,' Coughlin said. 'The realization of what camp is all about and just the idea of why we're here. We are here to work, prepare and become the best team we can be.' On Tuesday, the Giants received a small scare concerning the health of two players. Wide receiver Hakeem Nicks hyperextended his right knee in the afternoon practice, but he was able to walk off the field. He was to have a magnetic resonance imaging exam Tuesday night, the results of which were not immediately available. In addition, center Shaun O'Hara, whose left ankle swelled after Sunday's practices, visited the Hospital for Special Surgery in New York, but an MRI revealed no new injury to the ankle. Otherwise, the Giants' crosstown rivals, the Jets, have commanded headlines in the New York tabloids because of the Darrelle Revis holdout. Next Wednesday, HBO will broadcast the first episode of 'Hard Knocks,' which features the Jets this year. The Jets do not seem to mind the added attention. Within the National Football Conference East, other teams have had their share of dramatics. Dez Bryant, the Dallas Cowboys' first-round pick, sprained an ankle. Albert Haynesworth of the Washington Redskins has become a punch line in the NFL for repeatedly failing a conditioning test required for him to practice. Meanwhile, the Philadelphia Eagles are breaking in a new quarterback, Kevin Kolb. 'We don't need all the he-said, she-said and the media and press,' defensive tackle Jay Alford said. 'At the end of the day, you've got to play football.' Three days into the unofficial start of the season, Fewell, the new defensive coordinator, has caused the biggest commotion. His piercing voice cuts through practices, and his hot-potato drill Sunday in the first practice created a buzz. In the drill, players gather into different groups and quickly pass the ball to each other in a circle. The player who drops it is out. Last man standing wins, and the winners of each group advanced to the final circle. (For the record: Sha'reff Rashad defeated Mathias Kiwanuka.) Still, the Giants have serious football-related work to do in Albany. Last season, they closed the season with a 3-8 run, a collapse marked by porous defense and a rushing attack that, well, did not really attack. But this summer, the Giants are a rarity among some teams because they can use training camp to focus on football. And that suits them just fine. 'Distractions kind of take away from the energy of the team,' tight end Kevin Boss said. 'Quiet is good.'
