When Mazzetti decided not to play for the Cleveland Browns after they picked him up off the waiver wire in 1981, he joined the ABC television affiliate WSB-TV in Atlanta as the sports reporter through 1982, when he decided to come out of "retirement" and signed on as a free agent with the Boston Breakers in 1983. Mazzetti played all three seasons with the Breakers, where he was selected to the All-USFL team his first year and also became the subject of a pro football trivia question in the process – the first player to score a point in the USFL, on a 30-yard field goal in the Breakers inaugural game against the Tampa Bay Bandits. Mazzetti moved along with the Breakers to New Orleans, then to Portland, wrapping up his football days there in 1985.
