Glazer began his sports career as a reporter at the New York Post in New York City. He worked his way up within the Post organization by developing access to players and agents. He also wrote articles for the Giants Newsweekly produced by longtime New York Giants correspondent Dave Klein. Among his first sources were NFL agent Jimmy Sexton's New York representative, Peter Flach. Through Flach he became friendly with NY Giants cornerback Jason Sehorn and NY Jets cornerback Aaron Glenn. Through Sehorn he became close with current Fox analyst and former NY Giant, Michael Strahan. His controversial style and his commitment to be first with a story earned him the trust of some New York-based players and executives within the league.
