Michael Porter Jr.’s primal scream rang all the way to Denver on Thursday night. When Jamal Murray elevated for a fourth-quarter jam — a sequence which started when Porter blocked a Pacers shot off the backboard — it was a perfect example of the joy the Nuggets have found over their last four games. They closed the first half of the season with a 113-103 win in Indiana on Thursday night to extend their winning streak to four and improve to 21-15 on the season.
