Mayo Gaelic football boss James Horan is the latest inter-county manager to voice his scepticism at the new experimental rule changes.
Mayo are busying preparing for their FBD League campaign with Leitrim first up this weekend but Horan is unsure about how the new rules will work given the already considerable workload for referees.
"Let’s see how they are. Look, I wouldn’t be a fan of them. I think they’re a little bit crazy, to be honest," said Horan, speaking to Mayo GAA TV.
I don’t know what we’re trying to do to referees. How they’re going to be refereed, I just don’t know. You’ve seen it in quite a lot of games already where they’ve been used. They are going to be a struggle.
Carlow boss Turlough O'Brien and Monaghan's Malachy O'Rourke have also expressed concern about the effectiveness of the rules.
Gobsmacked with proposed rule changes .... and trialing them in the NFL???????

As far as his return to management is concerned, Horan did provide a note of optimism for Mayo fans, citing several young developing players as "ready."
We have some very exciting talent in Mayo. We saw that throughout the U20 campaign last year and some of the players that have come through the underage structures are very exciting. Colm Moran, Conor Diskin, Ryan O'Donoghue injured at the moment but really looking forward to seeing him come back in.
