Denver Nuggets coach Michael Malone quoted former Houston Rockets coach Rudy Tomjanovich after watching his team level their Western Conference semifinal series on Sunday, saying: "Never underestimate the heart of a champion."

The Nuggets levelled their series with the Minnesota Timberwolves at 2-2 with a dominant road performance, triumphing 115-107 at Target Center.

Denver never trailed after taking a 23-22 lead on Aaron Gordon's three-point play near the end of the first quarter, stretching their advantage to as many as 18 points early in the third.

While Minnesota pulled within seven with just under two minutes remaining, they failed to make another basket as the Nuggets levelled things up ahead of Game 5 on Tuesday.

Gordon amassed 27 points on 11-of-12 shooting while NBA MVP Nikola Jokic had 35 points, with 16 of those coming in the fourth quarter.

The reigning champions are now slight favourites to reach the NBA Finals as they prepare to host Game 5, leading Malone to hail their mentality. 

"What I found is Rudy T is right, man, 'never underestimate the heart of a champion'," Malone said, referring to Tomjanovich's infamous quote in the aftermath of Houston's 1995 championship.

"They were quick to write us off, but these guys, we won a championship a year ago. We went into Miami [in the Finals], won two games in a row. 

"This team has been tested time and time again, and we found a way to solve whatever's been thrown at us.

"This series is a long way from being over. We're not celebrating. It's 2-2, but what I found about our group is that they do believe in themselves. 

"More importantly, they believe in the man next to them. We have a group that is acting as you would hope a championship team would act."

Gordon echoed his coach's sentiments, saying: "I love it when people count us out.

"A lot of these guys have been counted out before in their careers. They've been the underdogs or the dark horse in their careers before. 

"So, I don't think it was anything new to the individuals. It was new to our collective, but I liked the challenge, and I'm glad we accepted it and put ourselves in a good position with home court."
