Like I said, the nature of the link between AFL and Gaelic football is what makes it very different.
Cool I don't agree at all and that's okay
There is no formal link outside of the international series which hasn't been played since 2013.
Yes there is an overlap with the skills required catching and kicking etc
There is plenty of overlap with other sports too. Basketball, Football, Rugby. Most likely the real transferrible skill is athleticism.
Players chop and drop sports all the time, the GAA lose far more players to rugby and soccer than they do to AFL.
Only from the perspective of the GAA which has hegemony Ireland. There is a couple of stories every few years about pro athletes coming home to play GAA.
Rugby and Soccer and Athletics and Swimming, Golf, Cricket, Tennis and pretty much every other sport would all say that its the GAA tries to keep an exclusive hold on talent. Christ we even get that talk about Gaelic Footballers who want to be hurlers.
i dont mean to sound overly critical the competition for resources is kind of natural if a bit sub optimal.
I don't really see what kind of agreement the GAA and the AFL could come to. That the AFL could perhaps use GAA facilities for training camps or scouting combines for an agreement to release players at end of season?
Again because of its Amatuer status the GAA literally don't have a leg to stand on so why would the AFL pony up any cash. Why should they.
The only parallel I see with NZ or French teams signing islanders is that they are offering a path to professionalism not available to them in their home place. That's it.
Your point about how scouting happens in a different code is more geography than anything else. Plenty of players get signed to Union from League and Vice versa. Plenty of historic linkages between those sports and even plenty of compromise rules exhibition series but it's the players who move codes not the associations.
As long as the players aren't under contract the GAA are toothless
