ASSISTANT coach Kevin Walters lashed an "un-Stormlike" Melbourne tonight after the NRL premier was humbled 40-8 by a half-strength Canberra at Simonds Stadium in Geelong. And capping their dirty night, the Storm suffered injuries to three players now likely to miss the club's World Club Challenge date with Leeds on February 22 in England. Scans tomorrow will confirm the seriousness of injuries to Matt Duffie (right hamstring) and Maurice Blair (left cheekbone), but Walters said Kevin Proctor's strain to a medial ligament in his left knee appeared "a bad one." Canberra coach David Furner was pleased with his team's progress and depth, but he, too, suffered an injury setback with 2012 NRL leading scorer Jarrod Croker also suffering a medial ligament injury. Walters hammered the normally impervious Storm defence, declaring it "non-existent" as the Raiders ran in eight tries to two. I know we had some guys missing, but to put a performance like that was very disappointing. "I think most of it was down to attitude -- a little bit down to the new interpretations of the rules, too - but preparation probably wasn't where it (should be) for a few guys and that reflected in the way they played," he said. The Storm has been a strong place to train and prepare well and that transfers into the games and certainly this week we were a bit off the speed. Walters said he didn't think Storm was running behind in its preparation, but that the hiding had come at a good time. I think it was a good wake-up call to everyone ... a really good reminder to playing staff and coaching staff. Melbourne, admittedly minus captain Cameron Smith, halfback Cooper Cronk and centre Justin O'Neill, looked badly in need of the run as the Raiders ran riot down the wings despite missing six players on All-Stars duty. But while Jason Ryles, Bryan Norrie, Proctor, Jesse Bromwich, Ryan Hinchcliffe and English international Gareth Widdop all had their first run of 2013, the 4500 crowd were most interested in superstar fullback Billy Slater. Slater, in his only pre-season hitout before the World Club Challenge, ran freely but was prevented from anything more damaging than his customary kick returns by a tight Raiders defence. Furner was hopeful Croker's injury wouldn't disrupt his start to the premiership season, but was confident the improved depth of his team would cover the loss if it did. We've got depth there from last year and that's important. You don't want to have too many injuries, especially to key players. I thought the experiennce those players received last year (and) you're just pleased the areas you've been working on during the pre-season that you are able to implement them during games.
