The emergence of Philadelphia quarterback Nick Foles has become one of the NFL's most surprising stories this season, but the Vikings say their primary focus lies with the Eagles running game.

Specifically LeSean McCoy, who leads the league in rushing with 1,305 yards.

"This dude is making moves," defensive end Jared Allen said. "He's like a human joystick right now."

The Eagles lead the NFL in rushing, largely due to McCoy, who set a franchise record with 217 yards rushing against Detroit in Sunday.

McCoy has rushed for 150-plus yards four times this season, the only player in the NFL to reach that mark more than once. He's also tied for third in the NFL in 20-yard runs with eight.

"Dynamic in every phase," defensive coordinator Alan Williams said. "Dynamic out of the backfield, dynamic when you have him bottled up. He's Houdini. You think you have him bottled up and he's right there. You look away and the next thing you know you're looking back at the film and he's 30 yards down the field. He's a fantastic football player. I don't know if he gets the recognition really that he should."

Several Vikings players compared McCoy to Detroit's Reggie Bush because of his versatility as a receiver.

"Yeah, that's fun," linebacker Chad Greenway joked about having to cover McCoy out of the backfield. "He's unbelievable. Reggie Bush-like. I think he's got different skills than Reggie. But just a matchup nightmare."
