We take a look at four big factors going into Sunday's huge Showdown XXXIX against the Crows...

Us…

The Power has made two changes to the side that defeated Collingwood by three points in Round 15. Jasper Pittard has been forced out of the side while Karl Amon has been omitted. In their place come form SANFL players Nathan Krakouer and Aaron Young.

This will be Krakouer's 50th game for the Port Adelaide Football Club.

FINAL TEAM: POWER BRINGS IN KRAKOUER, YOUNG

And them…

The Crows have also made two changes with Brodie Martin and Rory Atkins coming in for the omitted Nathan Van Berlo and Cameron Ellis-Yolmen. 

THREE CROWS TO WATCH: Walker, Dangerfield, Betts

What we loved last week

Under fire, Port Adelaide toughed it out. Collingwood could have won the match with their big second quarter and plenty of ball in the final term, but the Power's backs held strong and noteworthy games from Wines, Westhoff, Hombsch, Wingard and Gray were pivotal. It was a 'team' game as well, which have been few and far between this year.

What we didn’t…

The goal leaks still prove difficult to plug. Collingwood dominated the second term with the Power only able to stem the flow during time-on. In a heated Showdown, a goal-run could prove the difference between a win or a loss.

What we want

These have been two tough weeks for South Australia's AFL clubs, jointly and profoundly affected by the passing of Phil Walsh. But this is a Showdown, and there will be little love lost when the ball bounces at 2:50pm.

Everyone wants to win this one, no one wants to lose. We all know what Port Adelaide wants.

A win.
