What are the GAA doing to improve umpires?

Much of it has to do with poor umpiring and there was another example of it in Ennis, just 30 seconds in when there was hesitation about judging Shane Dowling’s free.
You could see the undue pressure it put on James Owens and his performance was affected by his uncertainty in what he was being told by them - especially following the sendings off when he again consulted with his umpires.
