==SRFC== 

 The sentence is saying that SRFC were regarded as Ireland's "big club". At the time referred to, the 80s, this was certainly true. In terms of prestige, success, etc etc. You asked for a citation, I provided one, but you didn't like it so you removed it. Eamon Sweeney is releveant because, a, he is paid to give his opinion on sporting matters in Ireland, b, he wrote a popular book o nthe subject.  

 What exactly is your opinion here anyway?  That SRFC was not historically considered the biggest club in Ireland? Why should anyone else pay attention to this? What relevance has it to the article?
