Corey Osinski helped Schalmont High School to what was, perhaps, the greatest run the Rotterdam school has ever had in basketball. From 1993 to 1996, Osinski, who was coached by his dad Ron, led the Sabres to an overall 65-9 record. Osinski was named to the section II class B all-star team all three years. He went on to play for Siena, where he was a four-year starter. Osinski was Siena’s co-MVP in 1999. After graduating from Siena, he played some ball in Portugal.
