Lakovic, nicknamed the "Pit Bull" for his aggressiveness, turned pro in 1992–93, playing for three separate Colonial Hockey League teams, as well as the American Hockey League's Binghamton Rangers. After bouncing around the ECHL, Central Hockey League, International Hockey League and AHL for a few more seasons, Lakovic cracked the lineup of the National Hockey League's Calgary Flames in 1996–97. Dealt to the New Jersey Devils a year later, Lakovic would play only 37 NHL games before finishing his career with stops in the West Coast Hockey League, and finally the Ligue Nord-Américaine de Hockey before retiring following the 2004–05 season.
