People miss the point - its not about capping players for the sake of it. There are NO players here playing in a consistent professional environment - none fullfill these criteria
a) are fully professional
b) train with full professionals
c) coached by full professionals
d) play exclusively against other full professionals
the point is that there is raw talent there - there is potentially great/international players - and some like ex saint pats players like Doyle will go on and show that clearly in time.
the goal should be that the national coach is fully aware of the talent and potential talent emerging - it mainly takes a move to a full time environment described above (mainly england in our case) but if the talent is formed here (as it is) than its a national bosses job to know and monitor it.
Capping el players is a red herring and is irrelevant.
