The former Wexford footballer has gone against the grain recently by posting video clips online of some training practices from London sessions — giving fans a glimpse inside the workings of a county set-up.
For most bosses — club and county — such openness is the stuff of their nightmares.
Deely told SunSport: “It’s such a closed shop in some ways, the Gaelic world. I suppose my eyes got opened when I came over and started working in professional football.
“We’re constantly sharing our work. I’ve gone on club visits to Tottenham, Southampton and others. Then when we are playing away games you are going in and chatting to the coaches and sports scientists there.
“You have people like Des Ryan who is in with Arsenal, a good Galway man, and he is putting out articles as to how they developed their academy, their philosophy and the exercises they do. They are out there for everybody to see.
Difficult to interact with
Deely — who is also hosting a coaching and sport science workshop in Dublin this Saturday — admits it has been hard to strike up connections with other inter-county bosses.
He explained: “It’s so difficult to actually interact with a lot of the senior inter-county set-ups that you don’t even get a knock-back.
“At the moment, it’s just not in the ethos, people are afraid to what they do. Ultimately it’s not as if any team is doing anything massively different.
“If you listen to somebody like Roger Federer, after a semi-final win, he will sit down in preparation for a Wimbledon final and openly speak about what he thinks the tactics of his opponent will be for the final.
“He’ll talk about what he did well in that semi-final and what exactly he could have done better.
“He’s so open. Most of them are so open about their own game.
“For me as well, it’s about promoting the games. I suppose the GAA do fantastic work in terms of the children’s development plans from age six to teens.
“But I don’t think there are many resources out there for adult teams, because the senior inter-county teams never show anything, so where do you get your adult drills and stuff like that from? So we’re looking to sort of fill that gap.”
