Matt Williams' future as Scotland rugby coach looks increasingly bleak after internal criticism of the Australian and his staff from players.
Williams has won just one Six Nations match in 10 attempts
BBC Sport has learned that Williams attracted flak in a Scottish Rugby Union questionnaire given to players.
And the SRU's corporate affairs director, Mike Keohane, said: "It should form a very strong basis on which to make decisions.
"Some people have seized the opportunity to have their say."
The SRU canvassed player opinion for the first time to gauge their thoughts on the tournament and preparation following a poor Six Nations campaign.
A large majority of those asked found fault with Williams' methods.
Scotland have lost 14 out of the 17 Test matches they have played under Williams.
BBC Sport reported last month that Williams will not be in charge by the time of this year's autumn Tests.
However, the coach, who has a lucrative contract that takes him up to the end of the 2007 World Cup, insisted that he felt his position was secure and would not resign.
The SRU, at that time, refused to confirm or deny that a decision had already been made to sack Williams.
But news of player dissent may strengthen the case against Williams and make him easier to remove.
The fact that such a questionnaire was ever issued and then leaked also suggests an element of manoeuvring against Williams from within the SRU.
Keohane confirmed to The Herald newspaper: "A review of performance is something that has always been done.
"But, on this particular occasion, every individual involved in the international game and delivery of the Six Nations effort has been invited to contribute.
"I believe that the gathering of information is pretty much complete, so we are moving into an assessment stage.
"People were asked to say what they felt went well, what went badly, how we can improve things and whether there were any other comments."
