John Cullen played college hockey at Boston University.  Although he was one of their best players, he went undrafted in the NHL.  Cullen left Boson University as the then all-time leading scorer, and he would try out for the Buffalo Sabres, who chose him in a Supplemental Draft.  He didn't make the Sabres, so Cullen would instead join Flint of the International Hockey League, wherein the 1987-88 season, he scored 157 Points.  As you can imagine, that turned many heads.
