As a Western New York native, Schlopy, a barefoot placekicker, signed a contract with the Buffalo Bills in 1985. In 1986 he signed with the Seattle Seahawks where he had an outstanding pre-season but failed to unseat incumbent Norm Johnson.[2] A highly sought-after free agent, Schlopy again signed with Buffalo in 1987 feeling that was his best opportunity to win a job. The Bills were under new head coach Marv Levy and new quarterback Jim Kelly. After a spectacular pre-season, Schlopy did not get the opportunity to attempt any field goals in the regular season and was released. He was called upon several weeks later during the 1987 NFL Players Strike to fill in as placekicker for the Buffalo Bills, while Scott Norwood took part in the strike.[3] Schlopy attempted no field goals in his first two games, made one extra point and another extra point blocked. Schlopy played a crucial role in the Bills' win against the New York Giants, kicking two field goals for a 6–3 victory, the second coming with 19 seconds remaining in overtime.[4] In doing so Schlopy became one of 3 barefoot kickers in NFL history to win a regular season game in overtime. Schlopy's professional football career ended after that game when the strike ended and Norwood returned.
His son, Alex Schlopy, is a freeskier who won a gold medal at the 2011 Winter X Games in the big air contest.[5] His cousin, Erik Schlopy, is a former alpine skier who competed at three editions of the Olympics; through Erik, the Schlopys are related by marriage to swimmer and media personality Summer Sanders.[7]
