You can't put an exact measurement on experience. Most of your squad experienced the pressure of a grand final last year, while none of our young players bar Symes have had that experience, and it's a priceless one to have. The Power should be able to respond to a pressure situation (which the Showdown most certainly is) better than the Crows since they have been exposed to far greater pressure before; Adelaide's stocks haven't which makes it a new experience for them.
Plus if you really want to look at numbers, you only have to look at the structure of the two sides to see that Port Adelaide has a clear experience advantage where it matters. In the ruck division, arguably the most important part of any squad, Adelaide had two ruckmen with 20 games' experience between them, one of which went off injured halfway through the game, and was a second gamer at that! This left Jon Griffin in his 18th game to compete against Cox and Seaby. Compare that to Port's ruck division: Brendon Lade 197 games, Dean Brogan 102, that's a fair gap there (without even looking at age). Then look at the main midfield mix used by both teams. For Port: Kane Cornes 142 games, Shaun Burgoyne 131 games, Dom Cassisi 109 games, David Rodan 92 games, Steven Salopek 65 games, Pearce 52 games, Travis Boak 15 games. For the Crows: Doughty 121 games, Thompson 111 games, van Berlo 55 games, Porplyzia 28 games, Symes 22 games, Vince 12 games, MacKay 2 games. As you can see there is a much better balance of experience in the Port Adelaide midfield with the Crows line up swayed towards inexperienced youth (I discarded Chad Cornes, Peter Burgoyne and Tyson Edwards here as iirc they weren't mainstays in the middle on the weekend). In that crucial midfield, including rucks, the advantage to Port Adelaide is so clear it isn't even funny.
Also if you truly believe that it's always the -best- sides that play off in the grand final you have rocks in your head. That is a foolish, misleading, narrow, simplistic view to take and you know it. The fact that Port Adelaide was in there last year prove this.
