Paul Roos’ call to use the rest of the AFL season as a dress rehearsal for 2015 is giving Melbourne a shocking case of stage fright.

The Demons were terrible on Saturday against Geelong in wet conditions at the MCG, dropping away badly after quarter-time for a 66-point drubbing.

Cats utility Steven Motlop starred with 26 possessions and a goal, while key forward Tom Hawkins kicked three goals in the 14.18 (102) to 5.6 (36) win at the MCG.

On Friday, Roos said starting with last weekend’s match against Fremantle, he was using the latter part of the season to assess his players.

He called their last seven games a dress rehearsal for next season.

Fremantle thumped Melbourne by 63 points in Darwin and Geelong similarly were able to do what they wanted.

While the Cats were in control from the start, Melbourne kept the game tight and restricted them in the first term.

But Shane Kersten’s goal on the quarter-time siren was a bad sign of what was coming.

The Cats kicked 8.2 in the second term – their best quarter so far this season.

Melbourne did not kick their first goal until the 17th minutes of the second quarter, when Jeremy Howe went forward.

Howe kicked another four minutes later, but the Cats responded with the last four goals of the half.

Geelong led by 59 points at the main break and cruised through the second half as the two teams kicked three goals apiece.

Young midfielder Adam Riley impressed for the Demons, while Jack Viney broke even with Joel Selwood after going on him late in the first term.

Selwood dominated in the opening quarter with 14 disposals.

The easy win continued Geelong’s total domination of the Demons.

Since Melbourne last beat Geelong in 2006, there has been a draw and now 10 Cats wins.

The Demons have gone through seven coaches in that time, while Geelong have won three premierships.
