Lack of detail in the Australian Crime Commission's report is an "extraordinary attack on Australian sport" according to senior rugby league figure Phil Gould.

Penrith general manager Gould, whose NRL club is being investigated by the league's independent auditors, was one of several sports identities to criticise the ACC on Friday for its broad-brush approach that tarnished all players.

Gould says it was unfair for the ACC to outline widespread doping in Australian professional sport and links to organised crime without providing more clarity.

"This report from the Crime Commission is full of words like maybe, could be, suspected and potential," Gould told Channel 9.

"Nobody has been named, no club has been named and no sport has been named.

"It's a broad-brush condemnation of Australian sport everywhere.

"At the moment everyone is guilty and I'm not sure, even if they find pockets of illegality, how you repair the integrity of everyone else who is in fact innocent."

NSW State of Origin coach Laurie Daley, in Brisbane for the All-Stars game, said it was sad that every professional athlete had been "tarnished".

"Until you know more detail, I'm like everyone else - I am left in the dark a little bit," Daley said.

"You'd like to know what the charges are or where we actually sit in terms of what's been revealed. At this stage nobody is really sure.

"Until you really know, it's all speculation."

Former AFL coach Paul Roos believed the ACC could do more to improve the reputation of clean athletes and sports.

Roos said there was no need to name names in the investigation but that there must be clarity on just how widespread the problem is.

"It's made a blanket statement," Roos told Fairfax Radio.

"I would have liked to have heard 'look we have 35 examples across four codes, we're not going to give any details of names clearly because we're still investigating'.

"Obviously there must be some logic behind what they did but certainly it sort of throws everyone in the pot."

Former prime minister Kevin Rudd also spoke out about the issue.

"The core challenge now is to establish the facts," Rudd told the Seven Network.

"Which players, which clubs - because I'm a bit concerned about every person out there who we've all watched, admired ... is now walking around with a total cloud over their head."
