Raiders prop Shannon Boyd.

Another week down and another big lead blown by Canberra and prop Shannon Boyd said the team can only blame the person in the mirror for their failure to make the finals for the fifth time in seven years.

The Raiders again experienced a dramatic second-half collapse as they watched their 14-point lead against Penrith evaporate before losing 40-31.

It's amazingly the fourth time this year the Raiders have lost when leading by 13 points or more.

But rather than blame contentious referee calls or other outside influences, Boyd said every player in the 17 needs to be more "accountable" for their level of play.

"Everybody's sort of down and we can't really put our finger on what's going on," Boyd said.

"But it's something we really need to fix up here or otherwise it's going to be a big struggle for the rest of the year.

"We're probably the best attacking team in the comp, we can score the points, but whether we're getting comfortable or what I'm not sure but we're leaking way too many points at the critical times in games.

"We're just to really start having a look at ourselves and get some accountability for us to do our own role."

Boyd said the side is perhaps placing too much pressure on themselves as scrutiny intensifies around their poor record against top-eight sides, which now stands at 0-9.

"It's not like we haven't been talking about it the last few weeks or since the start of the season, I don't know if we're over-trying and putting too much pressure on ourselves and forcing errors or mistakes by trying to do too much," he said.

"If we can take a step back and do what we do well for the 60 minutes for the 80 minutes then we'll go a long way to winning games."

Boyd said he was disappointed with only playing 30 minutes against Penrith but said he pulled up fine after returning from a calf strain.

Joey Leilua said he would happily give back his hat-trick against the Panthers if it meant the team was not faced with the same question they have faced this season, how to close out games.

"We've got a lot of reviews going on and we just need to focus on what we need to get better at," Leilua said.

"I think that's getting better at completing our sets, we've got to do that first and then hopefully we can win some games.

"I try and forget about straight away after the game but it's hard when you lose like that leaking so many points."
