The Melbourne Storm.

Melbourne skipper Cameron Smith has defended his coach in the wake of the Storm's second loss in three weeks to the Wests Tigers.

Melbourne let a six-point lead slip late in the match before Benji Marshall snapped a field goal to bring back an all-too-familiar feeling for the boys in purple this season.

In Bellamy's 400th NRL match, the Storm struggled to control the ball and finished with just a 65 per cent completion rate.

When asked where the responsibility for the loss lay, Smith was quick to defend his coach.

"It's on us as players it's got nothing to do with this bloke here – Craig and his staff prepare us as good as anyone could," Smith said.

"Craig gives us everything we need to go out there and play well, the players just aren't taking ownership on that.

"The ball control from us tonight was just awful. It has been all season. Until players in our team understand that you can't win without the ball, this is going to continue happening."

Bellamy said the loss felt "a lot like last week" and echoed the words of his captain.

"We are just not controlling the ball. I was happy with our defence but when you can't hang onto the ball, it's very disappointing," Bellamy said.

"The season could slip away on us if we don't get that right. Individuals need to start taking responsibility."

Following the departure of star playmaker Cooper Cronk to the Roosters, Storm halfback Brodie Croft is yet to stamp his mark on the number seven jersey.

After another shaky performance, Bellamy said it "certainly wasn't one of his better games" and gave no assurance Croft's position in the side was safe.

"We'll go back, look at the film and make a call from there," he said.

The Storm have just six days to prepare for their round six clash against the Newcastle Knights.
