Five observations on the final weekend of the NFL season:
1. The top two seeds in the NFC go into the playoffs with 13-3 records and backup quarterbacks, but that is the only thing the top seeded Eagles and second seeded Vikings have in common. The Eagles have to be worried if they can win with Nick Foles at quarterback. He only played a quarter in the team’s ugly 6-0 loss to Dallas and was only four of 11 for 39 yards and pick. Meanwhile Case Keenum played most of the season, going 11-3. The Vikings seem the better bet in the playoffs with Keenum than the Eagles are with Foles. The Vikings also could become the first team to play the Super Bowl in their own stadium.
