In 1990-91, Brown led the Blues defense in scoring, as he had 12 goals and 59 points in 67 games, as he missed nearly a month of the season due to broken left ankle, and was third in overall team scoring, only behind Brett Hull and Adam Oates, as the Blues finished with the second best record in the league, getting 105 points. In the playoffs, Brown continued to be very productive, scoring three goals and 12 points in 13 games, however, the Blues were upset by the Minnesota North Stars in the Norris Division final, losing in six games.
