Pat Spillane thinks the GAA has got the new playing calendar "all wrong".
In a move to better promote the club game, the All-Ireland football championships are set to be completed by the end of July next year.
It means that next year's decider will happen on July 24 - a first football final in that month since 1908; while replays in the football championship have been scrapped except All-Ireland finals.
But Spillane believes that the GAA are shooting themselves in the foot.
"Next year, for six months, there'll be no more inter-county football," he told RTÉ's Sunday Sport.
"We're taking our high profile games, which are inter-county football and hurling, out of the shop window for six months. [There'll be] no opportunity to generate money, no opportunity to generate a high profile for the game, for Croke Park, and for the players.
"Croke Park, from July on, will only have Ed Sheeran kicking a ball around; it's crazy.
"I can see the idea behind a split season, and it's vitally important that the club and inter-county player is facilitated, but I think the real way to go is to alternate. That ensures all year round, top-class, high profile GAA.
"So, for example, for the first six months of the year you'd have club hurling and inter-county football; for the last six months you'd have club football and inter-county hurling.
"The following year you alternate it, which means GAA all the year round.
"I think it's a complete own goal for six months to take our high profile [off]. While club matches are brilliant, they're low profile, parochial, they don't have a national profile, or a revenue-generating capacity which we need for the association.
"I think we need to address the calendar."
