The St. Louis Rams have really turned up the heat on defense, and that's not good news for Arizona Cardinals QB Drew Stanton. The Cardinals come into St. Louis tonight as underdogs, despite their 10-3 record. I think that we should see two of the premier defenses put on a show tonight in St. Louis.

Here are my keys to the game:

1. Rams Pass Rush - St. Louis has sacked opposing quarterbacks 13 times in the last two weeks, but that's not quite as impressive as holding the opposition scoreless in those two games. That's right, the Rams haven't allowed a single point in either of their last two games.

2. Drew Stanton - He's no Carson Palmer! Stanton has thrown four TD passes and five INTs in his last four starts.

3. X-Factor - These teams have a history of playing low scoring games, the under is 9-4 in the last 13 meetings.

Selection: This is a play on ARZ@STL to go UNDER the total (5*)
