The Philadelphia Eagles are coming off an upset win over the Patriots in New England last Sunday, and I believe that sets them up for a massive let down at home against Buffalo. The Bills won at home by a score of 30-21 over the Texans last week, and they have a history of playing well against the Eagles.

Here are my keys to the game:

1. Chip Kelly - His days in Philadelphia may be coming to an end. It appears that his players have quit on him, and he hasn't made many friends in the short time he's coached in the NFL. LeSean McCoy doesn't want to shake his hand, and DeMarco Murray has been rumored to be taking up his issues with the Eagles owner. Murray led the league in rushing last season, but Kelly doesn't appear to have much use for him in his offense.

2. Previous History - The Eagles have failed to cover the spread in five of their last seven home games, and they've only covered once in their last five meetings with Buffalo.

3. X-Factor - Sammy Watkins has battled injuries all year, but he appears to be getting healthier, catching 14 passes for 267 yards and three TDs the last two weeks.
