The Philadelphia Eagles and Arizona Cardinals have each escaped with a pair of wins each by the skin of their teeth, but one string of success will have to come to an end Sunday in Phoenix.

Of the six 2-0 teams left in the NFL, no team has beaten their opponents by slimmer margins than the Eagles and Cardinals. Philadelphia became the first team in NFL history to win both of their first two games by a margin of one point, while Arizona has won by four and two points, respectively. But that doesn't mean the wins haven't been quality: both teams have knocked off Super Bowl contenders, with the Eagles coming back to beat the Baltimore Ravens and the Cardinals becoming the first team ever to beat the New England Patriots in their home opener at Gillette Stadium.

All that leaves pickers with mixed feelings about the matchup between the two unbeaten squads: ESPN's 12 pickers are split down the middle with six siding with Philadelphia and six picking the Eagles. CBS also went half and half, with four picking each side. Yahoo is also mixed, with a pair of pickers choosing Arizona while Jason Cole and the site's pick'em pool have sided with the Eagles. A slim majority at USA Today sides with the Eagles. ESPN's Accuscore and pick'em pool both chose Philadelphia. The consensus is that this showdown between undefeated squads will be one of the weekend's closer affairs.
