The National football league got underway last weekend with four experimental rules being trialled.
The advanced mark, The 20 metre line kick out, the forward side-line kick and the sin bin will all be used during the duration of the league.
Shannonside FM GAA analyst Frank Brady believes waiting for a break in play for players to return after their sin bin time has elapsed is unfair.
Meanwhile Dublin manager Jim Gavin has criticised the G-A-A for not having “a clear vision” for the future of Gaelic football.
The All Ireland wining boss has also hit out at managers for their public opposition to the controversial hand-pass rule.
Gavin feels the experimental rules should have been introduced across the board.
