West Coast have laid bare the huge task facing Melbourne coach Paul Roos in the AFL with a 93-point Demons demolition.
A knee injury to star defender Shannon Hurn was the only lowlight for the Eagles in the 18.15 (123) to 4.6 (30) thrashing on Sunday at the MCG.
Luke Shuey and Nic Naitanui starred in the midfield and Josh Kennedy kicked four goals.
It is the biggest loss Roos has endured as a senior coach, beating the previous-worst margin of 73 when he was at Sydney.
By contrast, the Eagles were ruthless a week after also easily beating the Western Bulldogs by 65 points.
Hurn was subbed out in the second term after suffering the injury in the first few minutes of the match.
The Eagles took control from the start and kicked four goals in 13 minutes, putting the Demons out of the contest.
West Coast bullied Melbourne at the clearances, winning them 13-3 in the first quarter.
When the Eagles weren’t surging forward, Melbourne were compounding their own misery by turning the ball over.
Five of the first eight Eagles goals were direct results of the Demons coughing up possession.
Melbourne kicked one behind in the first term as West Coast took a 40-point lead.
The Demons did not kick their first goal until seven minutes into the second term, through Shannon Byrnes.
He also kicked Melbourne’s second goal at 23 minutes into the third.
While it was a poor day for most Melbourne players, co-captain Nathan Jones again stood out with a gutsy performance in the midfield.
Jones, who has won the last two club best-and-fairest awards, was relentless and finished with a game-high 34 possessions.
