SPEEDY small forward Jamie Cripps is set to remain an important part of West Coast's evolving attack until at least the end of 2020 after putting pen to paper on a contract extension.

AFL.com.au understands Cripps has added two years to his current deal, which was due to expire at the end of this season.

The 25-year-old has become a valuable member of the Eagles' attacking structure since returning home from St Kilda in exchange for pick 40 at the end of 2012.

Cripps has kicked 128 goals from 105 games in a potent forward mix alongside dual Coleman medallist Josh Kennedy, Mark LeCras and Jack Darling.

But the zippy half-forward's pace and elite tackling have arguably been his greatest assets.

Cripps booted a career-high 34 goals as the Eagles made it to the 2015 Grand Final, however his pressure helped Adam Simpson's side become the League's best team at locking the ball inside their forward half.

West Coast sorely lacked speed and tackle pressure in attack last year but the addition of exciting youngsters Liam Ryan, Daniel Venables, Jake Waterman and Willie Rioli has helped address those issues.

With that quartet refreshing the forward setup, Cripps is likely to spend more time rotating through midfield and at centre bounces.

But the 121-gamer told AFL.com.au last month that he was also relishing taking on a bigger leadership role in attack and helping the Eagles' youngsters settle in.

"With big Joshy not in just yet we are looking pretty young in the forward line," Cripps said.

"Me, Lecca and Jack Darling, we are the older ones in the forward line, so it's exciting.

"The last couple of years I've tried to lift my leadership in games and at training.

"If I can give feedback I try to help out whenever I can, so it's good for my development as a leader."

While Cripps has re-signed, the Eagles will want to secure 2016 draftees Rioli and Waterman beyond the end of this year, and could soon seek to extend Ryan's contract beyond 2019 after an exhilarating start to his career.

LeCras, who is set to play his 200th game in round four, agreed to a one-year contract for this season after battling hip issues which impacted his form last year.

It remains to be seen if the 31-year-old will want to play on beyond 2018 but he has made an impressive start this year, booting five goals and averaging 16 disposals in the opening two rounds.

There are several other big-name Eagles set to fall out of contract at the end of this season, headlined by intercept marking star Jeremy McGovern.

McGovern has reportedly been targeted by Melbourne clubs with big-money offers, while Victorian wingman Andrew Gaff and South Australian ruckman Scott Lycett are also due to become restricted free agents.
