SUMMARY
Entering a Showdown as the underdog isn't a familiar feeling for Nathan van Berlo and his Crows teammates – the side has only finished lower than Port Adelaide on the ladder once since 2007. It's the reality this week though as the Power try to lock in their finals berth while the Crows hope to win back some respect. It's been a dog of a year for Adelaide and a Showdown whitewash is on the cards; can the "pride of South Australia" live up to its claim?

THE SIX POINTS
1. The Power might have lost three of the last four Showdowns, but their win earlier this season was a stinging blow. Down by as much as 31 points the Power clawed their way back to win by nine.

2. Port holds the overall advantage in these contests, leading 18-16 after taking out the first Showdown in 1997.

3. Of the 34 previous Showdowns, three have been held in round 19 of those particular seasons. Ominously for Port Adelaide, the Crows have won all three.

4. Kicking for goal has been a struggle for both sides in 2013, with the Crows and Power ranked 15th and 16th respectively for goal-kicking accuracy.

5. Port skipper Travis Boak has been in sensational touch this season. Boak topped the AFL Coaches Association voting last week for the Power and is their top-ranked player in the AFL's Official Player Ratings at number 40.

6. Almost one and a half million people have attended Showdowns at an average of 43,244 per game. The highest attendance for one match was 51,140 in round five, 2003 – surprisingly higher than the 50,525 who attended the 2005 semi-final Showdown.
