Craig Bellamy could not hide his disappointment in young Melbourne centre Curtis Scott's actions in getting sent off in Saturday's 24-4 loss to Manly, saying he needs to learn from his costly error.

Scott's send-off in the 52nd minute for punching Dylan Walker turned the match on its head and Bellamy felt it was out of character for the 21-year-old to lash out.

"He needs to learn from this," the veteran coach said.

"That's one thing you like about him - he gets out there and is really competitive. That's probably the first time he's done that.

"He'll learn from that. It will be fairly costly to us and him as well."

Bellamy labelled his side's error-riddled 24-4 loss to the Sea Eagles on Saturday night as one of their worst in recent memory.

The Storm's downfall was completing at 63 per cent across the 80 minutes, compounded by 16 errors.

"At the end of the day, I can't remember the last time we played so poorly," Bellamy said.

"Especially the second half, I was really disappointed. We did a reasonable job in the first half, but the second half was crap. It's truly hard to win footy games with that kind of completion rate."

The defending premiers dropped to a 6-5 record after the dismal display. Asked how the Storm will fix their stuttering season, Bellamy put it back on his troops.

"It's up to the players now. They need to sort out how we're going to fix it,'' he said.

"We've come up with some ideas as a coaching staff and put it to them, but they obviously haven't bought into that. We're obviously not seeing the importance of that at the moment."

After Scott receiving his marching orders from referee Henry Perenara, Sea Eagles pair Walker and Api Koroisau were both sin-binned for their role in the melee with 28:13 minutes left on the clock.

According to Fox Sports, Koroisau and Matthew Wright (replacing Walker, who was having a head injury assessment) returned to the field with 19:54 remaining in the contest.

Bellamy admitted he didn't fully understand the situation, and would leave the proceedings up to club management.

Storm football manager Frank Ponissi said it was unlikely the club would lodge a complaint at this stage given the margin of the defeat.

"The NRL will conduct a review of the timing of the dismissals and the process,'' a NRL spokesperson said.

"The responsibility of timing for sin bins is held by the clubs, although in this instance, it appears there were no club-supplied sin bin operators present at the venue."
