[1] Hoffman was the cox for the men's eight at the 1967 European Rowing Championships where the team won silver.

A supporter of the Olympic Project for Human Rights (OPHR), Hoffman provided Peter Norman, the Australian winner of the silver medal of the 200m track race, with his OPHR badge, which Norman then wore at the medal ceremony in support of the protest by Tommie Smith and John Carlos.

Hoffman then faced a disciplinary hearing by the U.S. Olympic Committee, where he was accused of conspiracy.

Hoffman went on to take a silver medal at the 1972 Summer Olympics in Munich as the cox of the eight boat.
