I think Loughlin was much larger..we had 2000 kids total, 50 kids in each classroom. I think half the guys in my frosh class ran track! We had a much bigger pool to draw from sportswise.Regis was much more well-known for academics than sports, certainly back in my high school days ('67-'71).
Now and then, they would field a decent team in some sport or another, but never a sports powerhouse, like a Laughlin was.
