Interesting how much is being made of this since they haven't had the sustained success like John/Don Bosco, Centennial, DeMatha, Aquinas-FL, Katy types. Won a lot of games with no state titles.
About where Murphy draws from ("recruits from their region"), if it's a talent rich area like Harrisburg, a team like McDevitt even as a AA is hugely advantaged especially since their is no other private school competing for the talent they get. Had some awesome teams and success despite size playing "up" in the Mid Penn Commonwealth with Central Dauphin, CD East, Cumberland Valley, State College. As they say, location, location, location.
To a lesser degree Berks Catholic is working towards that kind of dominance since the merger of Reading Holy Name and Reading Central Catholic
