"grew up playing for a club in Cork"
A lot of the players from CBC and PBC end up in either UCC or Con following the leaving, but if you're playing for a school, you're not allowed to play for a club.
So in Highfield, we had a couple of kids who went to PBC and CBC, but that was about it. They were usually players who didn't make the first team for their age grade earlier on, or had parents who played for Highfield.
If a player is really good, they're regularly offered a place by the schools, at which point they'd be lost to the club, remember losing Donnacha O'Callaghan to Christians, was a massive hit at the time
