Pat Spillane says that the GAA's Special Congress made the correct decision in voting against the B proposal on Saturday.
Speaking on RTÉ's Sunday Sport, the eight-time All-Ireland winner said that the proposal is good but needs to be tweaked to make it great.
The option received over 50% of the votes of the delegates but still fell short of the 60% required for it to be implemented.
"I thought the decision was a correct one," said Spillane.
"It's clear after yesterday that a majority accept that the GAA championship isn't fit for purpose. It's not working and we need to revamp the championship.
"It needs to be more competitive, we need more meaningful games for weaker counties, we must breathe life into it, and if at all possible we need to close that gap between the weaker counties and the stronger counties.
"Option A was never a runner. Option B gave you the choice of choosing between the lesser of two evils but it had too many flaws; it wasn't the ideal solution.
"The task force brought in these recommendations two years ago and an awful lot of water has gone under the bridge since then. We now have the split season of club and county which has been brilliant.
"Covid has also had a huge impact, particularly financially. There was no proper cost-benefit analysis of Proposal B.
"The other big problem was that overnight you were getting rid of the provincial championships, and the power of the provincial councils. Yes they would have existed but really only as a pre-season tournament before the league. The link between them and championship was gone and that was fatal.
"The idea of lower-ranked Division 1 teams losing out on a place in the knockout stages while a team ranked 17th or 25th in the league would go through... there were just too many flaws.
"Let's be realistic, society is very unequal. Communism and socialism were great ideas - that everybody should have equality - but they failed. Sport is a mirror image of society, where there's strong and weak, big and small etc.
"No matter what system you bring in, you're still going to get hammerings."
At this stage, the next step remains unclear but it seems certain that the 2022 All-Ireland football championship will involve the provincial tournaments, two rounds of qualifiers, and then knockout quarter-finals, as well as the Tailteann Cup for weaker counties.
The Super 8s will not return next year.
Echoing the words of Kerry GAA Chairperson Tadgh Ó Murchú, who said that changes should be made before another vote at the regular annual congress in February, Spillane added that a new plan is needed.
"We need a task force with the really bright, progressive people in the GAA who have no agenda," he said.
"We need to come up with that plan by Christmas and have two months of a roadshow selling it to the counties in Ireland. Then hold a full congress.
"We need change. What we have isn't working. Let's not kick that can down the road any further, and let's act quickly.
"Eventually the football championship is going to have to end up with two tiers. I would like the provincial championships to still have an input. How? I don't know, but the provincial champions should be rewarded.
I like the idea of a league format. Weaker counties need to improve. They need more games. They will only improve playing better sides.
"All 31 counties, as well as New York and London, who are involved in the football championship should have a chance to win that competition.
"You might play a round-robin of the weaker counties, and that would then feed into the latter stages of the championship.
"If you look at the hurling championship, and its tiers, the same weak counties are still weak. Every so often a Laois or a Westmeath comes up and plays in the top-level championship, but you saw this year that they got ferocious hammerings.
"So we need a tiered structure. We need a top 16 and a bottom 16. The weaker counties need more games against each other, but they also need meaningful games against stronger counties so that they can improve."
