From 1999 through 2005, Vikings coach Brad Childress was a top assistant for the Philadelphia Eagles, meaning his team played its NFC East rivals, the New York Giants, twice every season.
In that stretch, the Eagles started 0-4 against the Giants, then won seven of the final 10 games during his stay in Philadelphia. Then, with Childress as coach, the Vikings beat the Giants 41-17 last year.
In Las Vegas, where the line favors the Vikings by seven points, much of what determines the odds is based on how teams play against each other. Childress was asked if his past success against the Giants gives his team an edge in today's game that could decide whether the Vikings make the playoffs.
"Aside from the fact that, like you say, you have to win the game, years and teams are too different," Childress said. "There's too many personnel changes.
"I guess knowing the history between the two teams and the two coaches, it's interesting to see the systems attack -- the defensive system, offensive system. It paints some pictures that way."
Childress says he hasn't been associated with Giants coach Tom Coughlin in any close way, but he has strong respect for him.
"I have great respect for Tom because he's a solid, fundamental, nuts-and-bolts football coach and that's what I appreciate the most about him," Childress said.
Much of the Giants offensive success will depend on the performance of quarterback Eli Manning, who has come into his own.
