MINNEAPOLIS — Jamal Murray and Kevin Harlan perform a beautiful duet together. At the end of 20 series-shifting seconds, Murray planted his feet in front of the broadcast table and struck a pose while Harlan was leaning forward, enraptured by Murray’s swagger and shouting into a microphone being transmitted across the country. In those 20 seconds, the Nuggets had more than doubled their lead going into halftime of Game 4 against the Minnesota Timberwolves, a sequence that ultimately gave them enough separation in a 115-107 series-tying win Sunday night.
