57 wins. The most in it's history. The team, however, had an early exit in the play-off against Golden States. One of the knocks on Karl when he was with the Sonics is that he could rack up wins during the season, but only once could it go deep in the play-offs.
Karl is 6th in all-times wins amongst past and present NBA coaches. He does not have a championship ring. Karl's honor is the longest time a coach (25 years) has gone before winning that award. He is a two time cancer survivor.
