[3] Malavasi left to attend Mississippi State University, earning a degree in engineering while serving as an assistant under head coach Murray Warmath in 1952 and also receiving an Army ROTC commission.
Malavasi accepted the defensive line assistant's position with the Buffalo Bills on February 3, 1969 and stayed for two seasons under head coach John Rauch.
Malavasi left to work for the Oakland Raiders in 1971 under head coach John Madden, but resigned after just two years, citing the frustration with the team keeping him from advancing his career.
While he denied the charges, Malavasi was hired on June 5, 1973, as a defensive assistant with the Los Angeles Rams under new head coach Chuck Knox.
The following year, the team barely finished above .500 with a 9–7 mark, but the NFC West was so weak that the Rams won their seventh straight division title.
Entering the fourth quarter of Super Bowl XIV with a two-point lead over the heavily favored Pittsburgh Steelers, the Rams' upset bid came up short when they allowed two touchdowns and fell 31–19.
The Australian Kookaburras did a week-long training camp at Dominguez Hills in southern California before heading off for a tour of Europe, where they played three games.
During the 1981 season, Malavasi was set to do a weekly morning call-in segment with disc jockey Robert W. Morgan on the Rams' flagship station KMPC 710 AM.
