Myshkin was able to break up all of the defensive schemes in European basketball, due to his unique skill set.

While playing with CSKA Moscow, Myshkin won eight consecutive Soviet Union League titles, from 1977 to 1984.

Even though his team was a FIBA European Champions Cup (EuroLeague) regular, Myshkin never had the chance to play for the European-wide top-tier level continental title.

As a member of the senior Soviet Union national team, Myshkin led them to back-to-back EuroBasket gold medals in 1979 and 1981.

In 2013, he became the head coach of the Russian women's national basketball team.
