Kevin Kilmurray (Offaly football manager): I'm confused. This has been brought on by players and managers in the GAA. Mick O'Dwyer was one of the managers on the task force so I didn't want to knock the sin bin last Sunday (after the Laois versus Offaly match in Portlaoise) but it is a total farce.

All these wise men have to meet again before next Sunday. It was obvious that every man, woman and child in Portlaoise knew it didn't work. The sin-binning of Karol Slattery was the prime example. The linesman said he was the third man in but he tackled his own player.

The pick-up is a good idea. The kick-outs (with tees) are concise and clear and a couple of extra yards can be gained. Neither of these are barriers to Gaelic football but the sin bin is not football as I know it.

Also, the linesman's new role has to go. The whole idea of some new rules is to increase the pace of the game but anytime he got involved a mini-conference ensued which slowed everything down. Players were just standing around and spectators were getting frustrated. The linesman should only be used in the case of taking the man out.

Brian McEniff (Donegal manager and Rules Task Force member)

Like any new rule it needs to be played for a while. I didn't see any games with the new rules over the weekend as I was with Donegal against Fermanagh and we have not introduced it for the McKenna Cup because the university teams are in the Sigerson Cup and are anxious to play under the old rules.

It will have to be reviewed. When there is an over-zealous referee, God knows what could happen.

I was always an advocate of the sin bin. I saw it 35 years ago being introduced to ice hockey in Canada and it worked. It might not work in football but it is still only January.

It will have to be reviewed before the National League because it has not even gone to Central Council yet. Perhaps, it would be better if a red card or two yellows meant you go to the sin bin.

Paddy Collins (Westmeath selector and former referee)

I have not seen a game yet but having been a referee and looking at it from their point of view, I think it will be a terrible imposition on them. Having seen the full text of the proposed rule changes it is going to make life extremely difficult for them.

The linesmen who are referees at intercounty level will be able to handle their new responsibility but if it is to become law it will come in right across the board. When you move down the line it will put huge pressure on non-referees who are doing the line. Even if they are neutral they are not referees, yet they will be expected to intervene.

We play a challenge match tonight against Leitrim and we have Pat McEnaney coming in to referee the game so our players are prepared for our O'Byrne Cup match against Longford next weekend.

Pat McEnaney (Referee and Rules Task Force member)

I'm not convinced yet. It might need adjustment. I'm not sure that the association would have the patience. Is it too steep at 10 minutes? Should a second yellow card warrant the sin bin? Is the old way the best way? What's important is we look at these rules changes. If they don't improve our game drop them. What's also important is that we reduce the 60 or 70 free count per game. We need to be tougher on discipline and if the association is patient enough the training ground emphasis will switch to tackling the ball.

I was in Drogheda (at the Louth versus DIT match). The pick-up and tees worked well but there was some confusion about the sin bin, mainly with the mindset of the players getting sin-binned for yellow card offences. It was a bit messy looking and odd for our game but let's judge it over three or four games.

The mindset will have to change. Those on the sideline are up-and-coming referees so they have to learn to make decisions under pressure.

Paddy Canning (Dublin under-21 manager)

The sin bin is a very severe punishment for very trivial offences. Our full back (Nicky McGrath) was sin-binned twice and then sent off. He made two tackles, neither of which was malicious.

Obviously, the referees were instructed to sin-bin for trivial offences. It's going to take time as referees are confused.

One of our fellas (McGrath) was sin-binned just before half-time and we were told injury-time didn't count and that it was actual time only, so he couldn't come back until 10 minutes into the second half. There was a minute and a half of injury time.

The pick-up worked very well and speeded up the game but both our kicking tees broke after 10 minutes. The linesman pointed out to the referee we were not using them and we were threatened with the sin bin if we didn't use them. We kept using them but the ball was sitting wrong.

Regarding the injured player (having to leave the pitch at the nearest endline or sideline) who knows when a player is fit to go off?

The sin bin should be done away with or re-addressed.
