It's nothing new for McGregor, who's been subject to similar scrutiny at various stages of his tenure, but the club's recent run has seen also seen fans turn their attention to assistants Ben Hornby and Dean Young - widely regarded as the heart and soul of the club's 2010 premiership side.

Only a dramatic change in thinking from the board would see McGregor moved on this season with two more years to run on his contract, but a loss to last-placed Gold Coast on Saturday would really mobilise the pitch forks.

A full review awaits at season's end with changes to McGregor's support staff forecast, but Frizell says the criticism has gone over the top over the last month.

"We just find it unfair," Frizell said.

"Our fans are so passionate and there's always outside noise with people wanting results. At the end of the day some teams aren't going to be winning, some teams are going to be losing, so there's always a team that's going to be spoken about [like that].

"We just know within this playing group and these four walls that we have the staff there who do a really good job for us and they have been. We're just pretty disappointed in ourselves not putting in the performances that we want to because we know how much hard work they put into us as players.

"The easier option is to point the finger at the coaches and say it's there fault but, as a playing group, we need to pull our fingers out and have a real good look at ourselves and the way we've been going because, individually and across the board, we need to be better."

Frizell has spent time on what's been a long injury list for the club this season, missing five games early in the year after lacerating his testicle in round one, an injury that's left him wearing a protective cup.

His spot in the NSW side for game one was put in jeopardy by a nasty concussion suffered against Cronulla in round 13, while he's also nursed neck and eye injuries.

Playing through has simply added to his reputation as one of the NRL's toughest men, but he put the onus on himself to lift over the next five weeks despite the niggles.

"It's all part of footy, no one's going into a game 100 per cent," Frizell said.

"I'm going through pretty good to be honest. In the past I've probably played through or been out through a bit of injury but the ones I've copped this year have just been for one or two weeks.

"I've got no issues at the moment or distractions in terms of my body or anything holding me back from playing good footy. It's not ideal the position we're in from a team point of view or for me personally.

"You always want to be playing your best and when the team's not going well you want to be playing even better. I'm hoping I can finish off the season on a high."
