WARREN Tredrea and Mark Williams are a formidable, successful and groundbreaking team.

The pair has already shared a number of 'firsts', most notably mounting the dais as Port Adelaide's first premiership captain and coach.

So it was only fitting the pair sat united, side by side, as the Power celebrated another breakthrough, in the form of Tredrea's 200th game.

On Sunday, the skipper will become the first player to reach 200 AFL games for the Power.

"It's been an enjoyable journey," Tredrea said.

"In the early days, it wasn't a certain journey or one that was going to work out. Mark would probably agree that he was someone who showed a huge amount of faith in me when I didn't have many runs on the board."

Williams' faith received the ultimate reward with Tredrea playing a vital role in the 2004 premiership.

The four-time All-Australian credits the tough Port Adelaide coach with his unrivalled success at Alberton.

"From day one, when some people couldn't see that I could make it, or doubted that I was good enough, Mark certainly never thought that was the case," Tredrea said.

"He rode me as hard as anyone, to the stage that in the early days, I hated doing one-on-one training sessions with him. I remember one vividly at the start of 1997, I was the only one who rocked up to a 7am skills session because you had the option of 7am or 3pm. I offered to come back at 3pm but unfortunately that wasn't accepted. I proceeded to become physically ill at Alberton Oval, very early on just from him riding me so hard."

"Mark probably made me the player I've been able to be, just from lifting the bar and never being happy with what I've been able to achieve."

With 435 goals in 199 games, Tredrea is one of the greatest centre-half-forwards of the modern era and has led the club's goalkicking in seven of the past 10 years.

As the first South Australian to reach the double-century, Williams had high praise for the newest inductee to the 200-club.

"Tredders will go down in history, certainly in his first 200 games anyway, as the best player that's ever played for the club," Williams said. 

"His record speaks for itself - winning three best and fairests and coming second twice, four times All-Australian and I think kicking 420-plus goals in that period says he's one of the outstanding players of the AFL over his time.

“If we ranked his 200 games, 80 per cent of them would have been first-class games. Eighty per cent would've dragged us over the line and caused us to win."

Tredrea began his AFL career in 1997 as a member of the Power's inaugural squad.

Having played junior footy for the Magpies in the SANFL, it was a dream come true for the then 16-year-old determined to follow in the footsteps of father Gary, who played AFL for the 'other' Magpies, Collingwood.

The Power No. 1 described playing for his beloved Port Adelaide as a privilege.

"I'd like to think I'm someone that's worked hard and given everything to playing in the Port Adelaide guernsey. My privilege has been that this week, I've played 200 games for the club I've always supported."

The proud 28-year-old vowed to overcome a knee injury that kept the star forward sidelined for half of the 2006 season.

"By no means am I finished and I'd like to prove another point," Tredrea said.

"To prove that I've still got good footy left in me and there are a number of young guys looking forward to another opportunity. For them, Sunday is just another game, a blip on their radar. It just means a little more to me because it's 200."
