There was an intriguing spoil of battle on the top shelf of Ray Edwards' locker: a helmet that was unmistakably painted in the silver and blue of the Dallas Cowboys.
"That belonged to Anthony Spencer," Edwards said. "He gave it to me after the game."
Spencer and Edwards were defensive teammates and close friends at Purdue. Did that make the souvenir helmet part of a pregame bet?
"It wasn't a bet," Edwards said. "We just met on the field after the game and Anthony said, 'You beat us. Here's your trophy.' "
The Vikings opened as 2 1/2-point favorites and moved to 3, yet many legendary football observers made a case for the Cowboys based largely on this:
The Vikings' Brett Favre would have less time to throw facing the outside rush of Spencer and DeMarcus Ware than would the Cowboys' Tony Romo going against Edwards and Jared Allen.
Edwards put the lie to that analysis on the game's first possession. The Cowboys ran nine plays and had a couple of first downs, but in the process the Vikings' left end did the following:
Hurried Romo into an incompletion as he delivered the first big hit on the quarterback. Corralled running back Felix Jones for a 4-yard loss back to the Vikings 38. Then, on third-and-14, drilled Romo and caused a fumble that was recovered by tackle Kevin Williams.
