Best of luck to him if he goes. Tbh the IRFU might struggle to keep the eligibility rule if he does given Ross Byrne and Harry Byrne are gone (latter not confirmed yet). We’d be bare bones at 10.
How many have gone abroad and been a success? Donnacha Ryan one of the very, very few. Crowley would be well advised to look at the plight of Ben Healy, ignore the big contract and tip along in Ireland for the next 15 years. That’s if there is any truth to the rumours at all.
I don’t think there is a decent enough sample size since the rule was brought in to really say. Well at the calibre of Crowley anyway. Healy wasn’t at his level in Irish terms.
Top line internationals (or hyped younger players) leaving in the IRFU central contract / provincial era really are a handful. Wood and Murphy don’t count.
Going back 20 years with Leo Cullen for an example is a good indicator. Fly-half’s alone who have gone abroad since include Sexton, Madigan, Hanrahan, McGinty, Healy, Jackson - a lot to be said for the pensionable job with the IRFU.
Crowley would be mad to go now after Prendergast playing his way off the Ireland team over the course of the championship. He surely has to back himself to take that spot back.
