Can nothing be implemented in the GAA without a row?
Blowing the half-time and full-time whistle only when the ball has gone out of play looked like an eminently sensible experiment, but it led to two disputes last weekend, with Longford and Louth claiming they were victims of misapplication of the rule.
You know what very often happens in these circumstances? An experiment is deemed to be a failure if it leads to rows and is promptly scrapped in favour of the old rule which is regarded as the lesser of two evils.
Hopefully, that won't happen here because this is a worthwhile experiment where the implementation shouldn't really tax referees.
