Eagles' quarterback Donovan McNabb wrote in his blog on Tuesday that people shouldn't be underestimating the Cardinals heading into Sunday's NFC Title Game. Philadelphia lost to Kurt Warner's Rams in the 2002 NFC Title Game. "In order to get there then, we had to beat Chicago on the road in very frigid conditions," McNabb said. "This time, we had to go to NY and defeat the Giants in very cold weather. Like the last time, this week will be playing on the road, in a dome, against Kurt Warner and his high-powered offense." The Rams were favored to beat the Eagles then, but Philadelphia is picked to beat Arizona this time around. "Make no mistake, the Cardinals are a solid football team in all three phases," McNabb said. "I know our supporters want to discount their abilities based on the Thanksgiving Day game, but they shouldn't - the Cardinals had to travel here on a short week. I believe we have what it takes to match up with them, but we will have to play our best football. If we learned anything from our previous playoff runs, it's that we cannot let up and must play at a higher level each and every week. "I hope all Eagles' fans help us build our momentum each day so that we all reach a peak on Sunday. I hope a few of you can be there to join us!"
