False. When I played, we did not. Actually, the 3 Catholic schools that "feed" into Andrean in the Tri-Town area (St. Joe's in Dyer is no longer, St. Michael's in Schererville and St. John Evangelist in St. John) "sent" more of their "talent" to LC when I was in school (92-96) than the other way around.
The floodgates opened around 1998 when some of our home grown talent chose to go to Andrean (Brett Goins-QB and Rob Caldwell-RB/LB). I coached them both at Grimmer MS. Both fantastic young men. Rob went on to The Naval Academy and lead the country in tackles, IMSC.
One of those player's parents made it known that they were sending their child to Andrean because they did not like Coach Britton's option based offense.
