Teams that are in the playoffs can't be taken lightly but as far as the series between the Nuggets and Spurs is concern i think the Spurs has a good chance of winning that and if they play the Blazers which also has a good chance of winning their series against OKC, we can base on speculation on history on their head to head at the elimination which is even. Blazer vs Spurs in the second round would be a good series but it's not over yet on the first round.

Nuggets is on different level this year, so if ever the Spurs win this series, Nuggets will surely give them a hard time. In fact, my intuition is telling me that this series will lead to game 7. Tough match up btw.
Spurs have system that makes Pop a good executer, the squad needs to follow his leads and surely he won't disappoint them, I can agree to you with how Nuggets went to this far, they are already a different team with the goal to step forward, the quest still open for them as long as they are playing that hard, game to reach the do or die series will be more interesting to watch unlike those remaining matches where even they are still on, you can predict with honesty who will have the edge against one another.
Pop is one tough coach, we rarely find another coach like him in the future, and as much I really wanted them to win , and I know the Spurs have a huge chance to win this series, yet I also wanted the Nuggets to compete for the WCF. So, I guess both teams are really deserving to win. TBH, this is the only match up that gives my attention and interest. I'm even confused in which team should I place my bet lol.
