Melbourne will have to be at their attacking best to crack Canberra's new-look defence and continue their recent NRL domination, Storm coach Craig Bellamy says.
The Storm have won six of their past seven clashes but ahead of their Friday night meeting in Canberra Bellamy says the Raiders are a different proposition this season.
Canberra's defence in their opening 21-0 win over Gold Coast looked much improved on the back of their smaller but more mobile pack.
"I talk to Rick (Raiders coach Ricky Stuart) quite regularly and one of the areas that they wanted to be better at than last year was defence and they certainly did that," Bellamy said on Thursday.
"The wet conditions were tough for both sides but to keep an NRL team to zero is a pretty good trick these days so they defended really well."
Bellamy says he will be looking for his big bodies - Jesse Bromwich and Nelson Asofa-Solomona - to use their size advantage to help the Storm dominate their opponents, who have shed 122kg Shannon Boyd and 123kg Junior Paulo.
"Boyd and Paulo are two of the other biggest players in the comp so they've obviously decided to change the style that they've been playing in the last couple of years," Bellamy said.
"All we can go on is their trial form - they won both their trials and they were very impressive last week so it looks like it's working for them."
