Minnesota Timberwolves wing Jimmy Butler was not happy after his team’s 109-97 loss to the Miami Heat on Friday night, saying that the club needs to start playing some actual defense. “I would think time and time after going through the film, you watching yourself constantly getting your (butt) beat on the defensive end, you’d get sick and tired of it,” said Butler, according to Jace Frederick of the St. Paul Pioneer Press. “I don’t think it registered in our heads like that.” Butler went on to take responsibility for the Timberwolves’ defensive shortcomings. “To me it doesn’t matter. We haven’t guarded anybody all year long,” said Butler, per Derek James of 1500ESPN in Minnesota. “So different mistakes, same mistakes, we have to eventually figure it out and want to play defense and stop trying to outscore the opponent. It starts with me and goes all the way down the line.” While Minnesota ranks eighth in offensive efficiency, it has been one of the worst defensive squads in the NBA, coming in at 25th in defensive efficiency, allowing 106.8 points per 100 possessions.
