Valley put out some Division-I basketball players over the years: B.B. Flenory, Pipkins, Pryor, Billy Varner. Burrell's Tom Myers played for Duquesne.
Har-Brack (which is smaller (pre-merger) and became Highlands), had Dick and Ed Modzelewski and Cookie Gilchrist all do well in college and spent time in the pros. For those not familiar:
https://en.wikipedia.org/wiki/Dick_Modzelewski - Outland Trophy winner, 2-time All-American, long NFL career.
https://en.wikipedia.org/wiki/Ed_Modzelewski - Sugar Bowl MVP, #6th pick overall NFL draft to the Steelers.
https://en.wikipedia.org/wiki/Cookie_Gilchrist - didn't go to college but went to the CFL first, then Buffalo Bills Ring of Fame, AFL MVP, first 1,000-yard rusher in AFL history.
Anyway, as far as Highlands goes, established I guess in the late '60s?, I can't think of one player that made an impact in college division-I football or basketball led alone the NFL. Not one. Anyone?
That’s some excellent research to mention Har-Brack. My Dad grew up with the Modzewski boys in Natrona and he called both of them the best athletes he’s ever seen given their size.
Highlands really has had no one. I believe in the early 2000’s they had a QB Matt Bonislawski who went to UCONN and UCONN was in the BE at the time. He was underwhelming to say the least. But, if you forced me to pick, I’d say him. But look at Riverview, Springdale, Leechburg, Plum...next to no one going D-1
