Chad Greenway was asked how the Vikings could completely dominate one of the best football teams in the NFL in beating the San Francisco 49ers 24-13 in Week 3, and then not play close to that well the rest of season, while that same 49ers team showed how dominant it can be by trampling the Bears 32-7 last week.
The Vikings looked like a Super Bowl contender that day, but they certainly haven't since.
"We put a lot of work into it and beat [San Francisco]," said Greenway, the Vikings linebacker who leads the NFC in tackles with 100. "We played the way we were capable of playing. Nothing surprises you when you prepare well."
Asked if the Vikings are playing as well now as they did when they beat San Francisco on Sept. 23, Greenway said, "I don't think we're there yet.
"But a victory over [the Bears] would be huge. It's a tough place to win, a tough place to play, they play their best at home, just like us at the Dome. They have a great football team and a great crowd; we have to take them out of it and give ourselves a chance."
The Vikings will visit Soldier Field on Sunday, and Greenway said: "It's the toughest place we probably have to play -- we haven't had much luck on the road in division games. Hopefully it will work out for us. We just have to try to play clean ball. The biggest thing is if we can create some turnovers and play clean ball."
Greenway believes the Vikings are in a better position to beat the Bears after their big victory over the Lions two weeks ago and the subsequent bye week.
"Nobody is a rookie anymore," he said. "They have a great team. I think we're more equipped [to beat them this year], but again, they're a great team on their home field, a place we've struggled as the visiting team [the Vikings haven't won in Chicago since 2007]. I think we're going to be focused going in and give ourselves a chance."
