The 6-1, 185 pound Bork rewrote the Northern Illinois University football record book with some help from end Hugh Rohrschneider during his junior and senior years at the DeKalb school. In 1962, Bork broke 14 college passing records ranging from yardage gained to best completions percentage. The following year he bettered 10 of his own records, tied one and set nine more for a total of 20. He also set a record of 244 pass completions during the 1963 NIU season.
He was the first college quarterback at any level to throw for 3,000 yards in one season. Bork first played football at Arlington High School, where he was an all-conference selection. Offered a basketball scholarship to Michigan, the athlete turned it down because he wanted to play football.
