Trout went undrafted in the
1981 NFL draft. That same year, he signed with his hometown team, the
Pittsburgh Steelers. During the 1981 season, Trout appeared in all 16 regular season games as the team's backup kicker, attempting 17 field goals, making 12 of them. He was released by the Steelers after the 1981 season. In 1983 he would sign with the
Philadelphia/Baltimore Stars of the USFL, where he was the team's starting kicker until the conclusion of the 1985 season. During his time with the Stars, he kicked for 116 field goal attempts, making 76. In 1987, the Steelers would re-sign Trout where he would appear in three games. He would only make two field goal attempts all season, missing both of them. Trout did, however, make all 10 of his extra point attempts. He was cut by the Steelers after the 1987 season. ==Post-retirement==
