He has kicked 50 more goals than any other Port Adelaide player this season and has taken nearly 80 more marks than any other Port forward and he is captain of the side.

But Warren Tredrea believes Port can win its first AFL premiership on Saturday at the MCG even if he produces a rare below-par game.

The Power will go in rank underdogs against a mighty Brisbane Lions' side, aiming to equal Collingwood's record of four successive premierships from 1927-30.

But in Tredrea, Port has a proven matchwinner and a player capable of causing havoc in even the best AFL defence.

In fact most AFL fans believe that the only thing that stands between the Lions and a record-equalling fourth successive premiership is a potentially huge game from the strong-marking Tredrea.

However the man who will lead Port into its first AFL grand final, in the absence of injured skipper Matthew Primus, does not see it that way.

"I think if I play my role and we kick a winning score then I have done my job," Tredrea said on Friday.

"I know in some games I haven't played well and the side has still won (the qualifying final against Geelong three weeks ago being a case in point)."

"That is the quality of the group we have got and we have come to a positive direction where we can have five players who don't play well - like last week when we had a number of players down (against St Kilda in the preliminary final) - yet still win."

"In the past it (over-relying on one or two players but in particular Tredrea) might have been an issue but now I don't think it's an issue at all."

"That's because within the side there are a number of guys who can chop and change and play a number of roles in the side and get us over the line."

However the stats tell a different story with Tredrea having kicked 80 goals for the season, while the next best is just 30 from Stuart Dew and Brendon Lade, while he has taken 186 marks with the next best - apart from key defender Chad Cornes and tagger Kane Cornes - being ruckman and part-time forward Dean Brogan with 107.

But Tredrea dismisses that stat as well as another crucial one going into Saturday's grand final - the fact that Brisbane rank first in hard-ball gets while Port rank last.

"Stats are stats and instead of looking at the overall stats we look at six or eight week periods and we have improved a lot in certain areas over that time," he said.

"It's well documented we are 16 (in hard-ball gets) and they are first but the difference is not that big.'

"We have made some dramatic improvements but tomorrow will tell how far we have come because tomorrow we are coming up against the best."

"But the guys are very relaxed and we know tomorrow is our day of destiny and if we are good enough we will be there at the end."
