Taking over the mantle of leadership from Orr, whose career was threatened by injury and who would soon leave the team, Park continued his great success under coach Don Cherry. Park had previously been an end-to-end rushing player attempting to imitate Orr, but with the Bruins he was told by Cherry to concentrate on defence. Getting over his unpopularity in Boston when he was a member of the arch-rival Rangers, Park settled in well with the Bruins, even hitch-hiking a ride from two teenagers at 1 am after his car ran out of gas, and Park later rewarded them with free tickets to the next Boston home game.
