What type of style did Stephen Larkham play?

The first answerer led you slightly astray. Larkham started his career as Fullback prior to Australia's 1999 RWC win. Rod MacQueen (the national coach at the time) shifted him into Fly-half and Australian fans were not happy.

Well, that decision ended with Australia winning a World cup and Larkham becoming the incumbent number 10 for Australia for 8 years. Larkham is credited with being the defining player for Australia's 1999 campaign, when he hit a 50-odd metre winning drop goal to beat South Africa in the semi final. Proof that MacQueen saw something that the fans did not.

Larkham had finese, but personally I think his strength was his brain, and all fly halfs need a quick one. He was incredible under pressure, saw the gaps to send his team mates through, and wasn't afraid to run it himself if nothing was on.

Be like him? Hard task. If it were that easy, we wouldn't be talking about him. But you can start by spending time on the theory in your game. Tactics, openings, psychology, and most importantly, having the balls to make the right decisions for your team, very, very quickly.

Larkham was an instinctive player which would make it hard to play like him. He was a great runner and passer with a great rugby brain and one of the greatest tragedies of modern rugby was that he was stuck behind a pack on roller skates which really deprived rugby fans of what could of been a true rugby genius. I would have loved to see Larkham and Carter square off with both behind decent packs. That would have been a real treat.

Larkham was excellent both as a fullback and a flyhalf. His great running abilities made an awesome counter attacker at fullback and he was also good under the high ball and strong defensiively. Fly-half was his best position however as this enabled him to truly utilise his skills and create for other players.

A little know fact about Larkham was that before super rugby started he was also a half-back

Larkham was never a fullback. I think you are confusing him with Latham. Larkham was a very skillful attacker finding gaps in defensive lines and using kicks to his advantage. A rugby back and a NFL back are completely different so no style could be adopted. If Larkham played NFL he would only be good as a placekicker

Larkham played with finesse, he was not an aggresive player he used his mind more than his power, he was also very elusive and would always present the ball to the opposition, making them think wether he was going to pass or going to run.

I disagree, Larkham was a great (and unlikely looking) athlete who made good decisions on the run. I think with the proper background he'd have been a good quarterback.

To play like him? Practice, practice, practice. Larkham was great because he didn't have to think about the basics, leaving him free to read the game. And a pinch of fairy dust.
