PICK: EAGLES
Running back
Eagles: Brian Westbrook, who has played with a sore knee much of the season, is averaging just 2.8 yards per carry since his back-to-back, 100-yard rushing performances vs. Arizona and the Giants in Weeks 13-14. Take out his 71-yard TD catch-and-run vs. Vikings and he's averaging just 3.6 yards per touch in the last five games.
Cardinals: The Cardinals averaged just 21.2 rushing attempts per game in the regular season, which was the fewest in the league. But they brought Edgerrin James out of mothballs late in the season and have been more balanced offensively. But James is 30 and isn't the runner he was 5 years ago.
PICK: EAGLES
Receiver
Eagles: Sure-handed Jason Avant has developed into a dependable slot target for Donovan McNabb. He's got nine catches in the Eagles' two playoff wins, six for first downs, including that huge, 21-yard, third-and-20 reception vs. Giants. But Avant and the rest of the wideouts need to become a bigger factor in the red zone.
Cardinals: Larry Fitzgerald is the best wide receiver in the league. He's big, fast, with great hands and body control. In the last four games, he's got 22 catches for 498 yards and five TDs. Anquan Boldin, who has missed three of the last four games with a hamstring injury, is expected to play.
PICK: CARDINALS
Offensive line
Eagles: Eagles finished 5th in the league in sacks per pass play this season. They gave up just one sack in their Week 13 win over the Cardinals, and have allowed only 10 in the last seven games. Their run-blocking, though, has been hit and miss. Their 3.97 yard-per-carry rushing average was second lowest of the Andy Reid era.
