Think of the era when the WPIAL was producing guys who went on to become college standouts n even pros, and the WPIAL playoffs were held at the Fitzgerald Field House and the Civic Arena televised on Channel 13, play-by-play by "Chilly" Billy Cardille):
Norm Vaniler (as the name was spelled then), Midland (and his teammate, Simmie Hill)
Stu Lantz, Uniontown
Dick DeVenzio, Dennis Wuycik, and Fran Kaufman, Ambridge
George Karl, Penn Hills
Wil Robinson and Gus Gerard, Laurel Highlands
Jack Marin, Farrell (I'm too young to have seen Willie Somerset and Brian Generalovich play for Farrell, but I know they played there)
Just to name a few.
