IF WEST Coast's forward mix looked predictable and stale at times last season, then it shouldn't lack for X-factor once Willie Rioli and Liam Ryan are introduced to a refreshed line-up in 2018.

But while the buzz around the untried goalsneaks has grown over pre-season, their line coach Jaymie Graham has noticed more than just an attacking chemistry that is improving with every session.

Defensive pressure has become a non-negotiable for small forwards, especially following the success of Richmond's mosquito fleet, and Graham believes trimmed-down Rioli and 2017 draftee Ryan will deliver more than just extra firepower.

"I do definitely see that (defensive pressure). Willie's got a really good balance," Graham told AFL.com.au.

"I probably hadn't seen it in Liam previously, not that I was watching too closely, but what we've seen so far in pre-season training is he has an impact defensively … and he's so quick.

"In the competition we've seen a bit of that and we think they can bring both sides of their game."

Rioli's first year at West Coast was ruined by two serious hamstring injuries, but such was the Eagles' desperate need for crumbing small forwards that he was mooted for a shock call-up during finals.

He was ultimately overlooked mostly due to a lack of conditioning, but has shed at least seven kilograms and is lighting up the training track this summer.

"It obviously helps being lighter, he can get across the ground more, but not only that, he's also learnt that it also helps you with injury prevention being in better physical condition," Graham said.

"So far, so good with Willie.

"He's ticking off the sessions and he's really putting his hand up to get a game early in the season.

"I think he's going to give us a different dynamic in our forward line – not only is he elite with his skills but he can bring some good pressure."

Ryan was a sensation for Subiaco before West Coast handed him a call-up to the AFL via pick No.26 in last year's NAB AFL Draft.

The high-flyer claimed the WAFL goalkicking award last season, booting 73 goals for the Lions, and hasn't missed a beat stepping into a professional environment.

"The chemistry, especially between him and Willie, is very good," Graham said.

"He's fitting in well and he's still got plenty of upside and a lot to learn, but it will be exciting to see the two of them fit and available and playing in the same team."

Rioli and Ryan lined up with what appeared to be the Eagles' first-choice forward group – minus injured spearhead Josh Kennedy (ankle) – during match practice this week and seem destined for round one debuts against Sydney at Optus Stadium.

After lacking enough variety with goalkicking options last year, West Coast hopes the dynamic duo can ease the unhealthy reliance on Kennedy and relieve some of the burden on veteran Mark LeCras coming off a year when injury impacted his form.

"With Lecca, it should take a little bit of pressure off if there's some other dual threats in the forward line," Graham said.

"It will be great to see them working together."
