They were both kind of hounded into those picks by the media though, if I remember rightly. I seem to remember McCarthy being almost gleeful back to the media later on when Connolly went off the boil a bit (you're not calling for him now etc.).
Having said that I think something similar would have happened this time, we'd have had a few bad results and whoever the manager was would have been forced to call a few younger players in to keep the press off his back.
We'd have also reached the knockout stages of the 2021 Under 21 Euros I reckon!
