The visiting teams (with better records) were all favored this Wild Card weekend, but in a pair of good games, the home teams pulled out upsets.
This was not really too suprising in some ways. Arizona has been good at home this year and was facing a team with less experience in key places, which might have been why the Falcons made a few two many mistakes. This included the clincher, after Arizona made a question call on second down, leaving it third and long, out of field goal range, the Falcons seeming to have a chance to have time for a winning drive. Nope. The Falcons defense, good much of the game, even after Arizona had a good Third Quarter, gave up the winning first down. 30-26 ... the safety by the way was arguably a good thing for the Falcons, changing field position with little affect on the score, especially given it was getting late in the game, so two TDs were probaby necessary.
San Diego was 4-8, helped by a dubious call in their second game, and an end of the game win (after a tying field goal came with enough time for Peyton Manning to win the game) against the Colts. That too was a national game. The Colts also started off lousy, but a long winning streak would have gave them a home game, if the Titans didn't have such a strong start. So, they had to travel to 8-8 SD, who got revenge against Denver for that zebra aided loss, after the Broncos' late season collapse. You know where Manning is told to "take a hike" in that amusing commercial. "Sweet," however, was the fate of SD, helped by great defense, punting repeatedly pinning the Colts near the goal line, the Colts not having enough time at the end of the game to win, and SD winning the toss.
Finally, SD lived by the officials this time, the Colts amazingly repeatedly committing penalties in OT, before a TD run clinched it. A key first down helped them earlier too, a questionable early challenge making it inapt for the Colts to challenge. Good thing, since even though SD outplayed the Colts, they made enough mistakes to give the game way, which would have been fairly typical for a team/coach that is known to fail to close the deal. OTOH, SD did knock the Colts out of the playoffs last year too. [Update: SD played the Colts tough generally of late] Both teams will have it harder on the road, but even one win is more than many thought either would get not too long ago.
As to the games later today, I guess the safe call is to think it will be a split, the Eagles losing probably helping the Giants get a weaker opponent, not some team who wants to pull a Giants, '09 style. The loser to winner bowl, Miami/Ravens (Ravens giving up Miami's one win last year) is probably the harder one to call. We shall see.
