Tomás Ó Sé believes Proposal B has some weaknesses but hopes it will pass at special congress as he thinks change to the football championship format is long overdue.
The league-based championship with the winners of Division 3 and 4 among 10 teams reaching the knockout phase is seen as the only one of two potential new formats with a chance of getting 60% support at Croke Park on Saturday.
"I'm sick of being it kicked down the line. Bring it in and change it," the Kerryman, now a selector with Offaly, told the RTÉ GAA podcast.
"The general consensus is that it's not perfect. The core issue is the principle that they want every team to challenge for the All-Ireland from the start. You don't put junior teams into senior teams because they don't have a chance.
"I think that the year is too short for what we want to achieve and to keep everybody happy but I still think that change is needed.
"I'd probably say that Plan B is not ideal but it's change and it's a start."

Ó Sé said that the main reason for change was that lower division teams are investing as much time and effort as All-Ireland contenders, only to exit the championship after a couple of weeks.
"There are too many counties in the country whose season basically finishes after the league," he said.
"I still think there are going to be hidings dished out at the far end of the summer, but it gives counties something more to look forward to.
"How many times have we seen the national league done and players heading off to America from so-called weaker counties? The interest just dies.
"I've seen it from a Kerry point of view and there has never been an issue with commitment. Stuff that you thought was a given in every county but it's not because they don't believe they have a fair chance.
"Standards slip all around because of it. But if there's something tangible they can actually have a go off, maybe we'll see standards improve.
"Because of the way football has gone, and the amount of time that has gone into it, you're asking players from Division 3/4 to put in the same commitment, level of preparation and professionalism with absolutely zero chance of winning anything.
"They need something they can actually achieve and the Munster and Leinster championship aren't that.
"I think change right now is good."
