They are the hot team, so conventional wisdom argues that they want to play this weekend. Nope. Incorrect.
They have been going full throttle for 11 weeks straight with their last 3 obviously on the road, and they could use a 'home game' this weekend. I am reminded of the Giants-Ravens Super Bowl 7 years ago. A #1 seed with the bye vs a wild card winner that played 3 playoff games, the last two games on the road. The Ravens needed some rest and (in retrospect) many felt that the week off benefitted the Ravens more. The Steelers also won the Super Bowl after winning 3 wild card games and getting the 2 week layover. So the precedent is there for the wild card winner to benefit more.
The only reason to think it will hurt the Giants is that you believe they will lose their edge and not have that focus which has gotten them into the big game. I can only counter that with a sense that this team is confident and they still feel they have a lot to prove. They know their job is not over by any stretch.
In the meantime, guys like Pierce, O'Hara, Burress, Madison, Ross and McKenzie all played through injuries and they will benefit from an extra week off. Seubert, despite having an MRI on a knee sprain, says he will play. Maybe they can get Dockery back. I do not think this layover does anything but help the gmen. Now if you are going to mention the TMZ report about Brady wearing a boot, his leg would have to be broken in 3 different places in order for him to be out of the Super Bowl if it were being played now, this weekend, or next weekend.
