Good luck definitely wasn't on the Eagles' side last year, with the star-studded forward line decimated by injuries.
All-Australian forward Mark LeCras was ruled out for the year after injuring his knee at pre-season training.
Mark Nicoski also had his season ruined when he tore his hamstring during the NAB Cup grand final.
And the damage was complete when spearhead Josh Kennedy was struck down with a serious ankle injury in round five, ruling him out of action for 15 weeks.
Despite losing three of their best forwards, plus wingman Andrew Embley for a fair chunk, West Coast battled on manfully to finish in fifth spot on the table before bowing out to Collingwood in the semi-finals.
The Eagles have now made back-to-back finals series since claiming the wooden spoon in 2010.
And if the club can avoid a repeat of last year's debilitating injuries, a fourth flag beckons.
"We've been building a team that's been a reasonable performer in the finals in the past two years," Worsfold said.
"But we don't want to be a reasonable performer in the finals this year. We want to be a strong performer. We want to be a lot better.
"Young teams in big finals can struggle.
"But I think we're out of that hump of saying we're a young, developing squad. We've matured beyond that."
One of West Coast's biggest strengths is their absence of a noticeable weakness.
The defence, led by skipper Darren Glass, is strong, reliable and flexible, with a number of shut-down players complemented by rebounders like Will Schofield, Beau Waters and Shannon Hurn.
The midfield, boasting the likes of Daniel Kerr, Luke Shuey, Scott Selwood, Matt Priddis, Andrew Gaff and new recruit Sharrod Wellingham, has the potential to become one of the best in the competition.
The ruck duo of Dean Cox and Nic Naitanui are already the league's standard-bearers, with the pair winning All-Australian honours last season.
And West Coast's fit-again forward line has the firepower to blow teams off the park.
Jack Darling, at just 20 years of age, booted 53 goals last season, and has the potential to reach 70 this year.
Kennedy and LeCras are proven performers who can kick big bags of goals, while opposition defences are further stretched when Cox and Naitanui spend their 'rest' periods in attack.
Even the little guys are dangerous, with Nicoski, Josh Hill, Brad Dick and Ashton Hams set to battle it out for the small forward roles.
Quinten Lynch's defection to Collingwood came as a slight shock.
But with West Coast possessing so many talented big men on their list, the Big Q will be easily replaced.
Most of the ingredients are there for West Coast to go all the way this year.
A sprinkling of luck might be all that is needed to ensure it happens.
