The Dundee United midfielder has intimated his organisation is inundated by complaints from its members who are dissatisfied with how the SFA are handling disciplinary matters.
Such a view seems pertinent to Rankin after his United team-mate, Gavin Gunning, lost his appeal against a three-match suspension which he had incurred after the SFA reviewed footage of the defender kicking Celtic's Virgil van Dijk off the ball. That led United to ban the BBC from Tannadice - a decision which has since been rescinded - but Rankin has remained forthright in his criticism of the whole disciplinary process.
The SPFA chairman wants the relevant parties to discuss how the existing system works and make amendments. It is just two years since the process was "streamlined" by the SFA yet Rankin is not satisfied. The midfielder - who was sent off controversially in a match with St Mirren last season - touched on issues such as the £1000 clubs must pay in order to appeal a decision, although his main gripe appears to be that players are being judged by individuals who have "never played the game".
It is a criticism which is prevalent in Scottish football. "There are reps at every club and players complain all the time about the system and the way things are going," said Rankin. "We need to stand up and be counted. Every player complains but it's not falling on deaf ears. We are trying our best to get someone on that panel who speaks for us. We need a voice.
"I've fallen foul of it before when I was sent off. I've only ever had one red card in my career and I thought about appealing it but £1000 is £1000 and, if your appeal is knocked because there's not a player on the panel to stand up on your account, then you lose that money. It's difficult when you've got people judging you who have never played the game."
The midfielder is confident that such concerns can be assuaged if the SFA agree to place a former player on to panels to discuss incidents such as controversial red cards. "There's not an ex-player on the panel and we are striving to try and get one on there," he added.
"There's an ex-referee and people from the SFA but we need a player in there with game experience to put across their opinion too. Whether it's an ex-player from years ago or someone who has just stopped playing recently, we need someone in there who can put across an opinion from a players' point of view.
"We are striving to do that but I don't know how close we are to getting that. Fraser Wishart [the SPFA chief executive] has been in talks and hopefully it will happen sooner rather than later because it's not just this club [United] that's suffered, it's other clubs as well. If we can get at least one ex-player on the panel it helps everyone."
The decision to suspend Gunning was taken after footage from television highlights showed him to kick van Dijk. However, Rankin is not convinced such a practice is being conducted fairly. "If you get someone from the tv companies going through each game with a fine tooth comb they will probably find something in each game that could get someone banned," he said. "We are looking to clean the game up but you want the best product on the pitch and that's not going to happen with players being banned all the time. We should be talking up the good not dragging the game through the mud."
That has informed his sympathy for Gunning, who will miss Sunday's match with Ross County. "Gavin's a big miss," he added. "It's hard to train knowing you can't play. But he's got to keep his head up and he's got to be ready when he can get back into the team."
