I'll probably be proven wrong about this.. But if the Cardinals wake from their slumber they could give the Rams a run for it. These two teams know each other well. And when two teams know each well sometimes the statistically lesser team can win. (Ask my Bucs about the Saints!)
The NFL getting greedy and adding 2 teams to the playoffs has made wild card weekend suck for the most part. It was like the first round of the college playoffs with 5 games instead of 2. The only good game was the Raiders/Bengals game. The rest where snooze fests.
