Bird was selected by the Boston Celtics with the sixth overall pick in the 1978 NBA draft.He did not sign with the Celtics immediately; instead, he played out his final season at Indiana State and led the Sycamores to the NCAA title game.

Celtics General Manager Red Auerbach publicly stated that he would not pay Bird more than any Celtic on the current roster, but Bird's agent Bob Woolf told Auerbach that Bird would reject any sub-market offers and simply enter the 1979 draft instead, where Boston's rights would expire when the draft began on June 25, and Bird would have been the likely top pick.

After protracted negotiations, Bird inked a five-year, $3.25 million contract with the team on June 8, making him the highest paid rookie in sports history.Shortly afterwards, NBA draft eligibility rules were changed to prevent teams from drafting players before they were ready to sign, a rule known as the Bird Collegiate Rule.
