Murray now an even bigger threat: Kaufusi

Storm back-rower Felise Kaufusi believes rising Rabbitohs star Cameron Murray is an even greater threat after switching from lock to right edge.

Murray arguably needed a couple of games to find his feet but was among his side's best player in the round three loss to the Roosters, scoring a try and setting another up to go with his 39 tackles and 123 metres.

"He's a quality player, it's going to be a big challenge, one I'm up for and I know he's going to be up for it," Kaufusi said ahead of Friday night's meeting between the two teams at AAMI Park.

"He's been playing really well, especially towards the back end of last year and early on this year, playing on an edge has made him more dangerous if anything so I'll have my hands full there."

Storm left-side forward Kenny Bromwich said the whole team needed to be on alert for the freshly re-signed Murray, who could end up anywhere across the park.

"He's a really good player; they get a lot of momentum off him, he's really crafty and good defensively too," Bromwich said.

"If he ends up either side or plugging in the middle at some point we'll need to do a good job on him because a lot of good things happen around him."

Kaufusi admitted the review after the Raiders game was "pretty full-on" and agreed with teammate Christian Welch's assessment that the club would need to find a way to adapt to the new speed and rules of the game.

"It's not us at all, we're always so structured, everyone knows their roles and when we're meant to be running or passing," he said.

"It's a big change for us. If we're going to compete this year we're going to have to make some changes. I don't know how that is, if that's less than structured, I don't know but we have to change something to the way the game's going.

"We're always looking to improve and learn from what's happened so if anything last week was a big learning curve so we're going to try and adapt as best we can.

"Not having the second ref in there really makes a difference, once you're on the back foot it really takes a few tackles to try and regain that structure or momentum; once someone pokes their head through or makes a break all hell breaks loose."
