In 1980 Dan Wood, who had been the head coach of the Tacoma Tides and was now the head coach of the Atlanta Chiefs, brought Chadwick to the Chiefs as a joint head coach. Following Wood's departure at the end of the season, Chadwick became the sole head coach the following year. The Chiefs folded after the 1981 season, but Chadwick remained in the city, becoming head coach of the newly formed Georgia Generals as they played their first season in the Second Division American Soccer League. After a successful season with what started as a scratch side, Chadwick returned to the NASL as head coach of Fort Lauderdale Strikers in 1983, signing with the team in September. He followed the franchise to Minnesota for the 1984 season and continued to coach the team through the last season of the NASL. In 1986, he coached the amateur Atlanta Datagraphic.
