The New York Giants schedule appears to be fairly difficult. The team plays the Seattle Seahawks, who have dominated the G-Men recently. In addition, a trip to face the Oakland Raiders becomes a steep hill to climb. Thankfully Big Blue takes on the Kansas City Chiefs at MetLife Stadium, which makes the game winnable.
A prime time tilt against at the Denver Broncos has definitely decreased in difficulty. But they still have to face the Detroit Lions, Tampa Bay Buccaneers and their NFC East foes.
As far as the easiest, well, there are not many choices.
