With Wisconsin having won a National Championship in his absence, Thomas remained with Team USA for the next season as they prepared for the 1984 Winter Olympics. He played through the entire season with the program and was even included on the Olympic roster, but he didn't play in any of the games. After a disappointing 7th-place finish, Thomas left the national team and returned to Wisconsin. The team had fallen off the pace after making three consecutive championship games and was now playing just well enough to not make tournament appearances. Upon his return, Thomas produced a monster offensive season, leading the team with 50 assists and finishing second at 63 points. He led all defensemen in the nation in scoring and was named an All-American. After Wisconsin was eliminated from the playoffs, he rejoined the US national team one final time at the World Championships, helping the team to a 4th-place finish.
