The only hard series that the Spurs are facing is the round one, but it seems they can take care of the Nuggets.
If they will pass through the 2nd round, they will be facing either the Blazers or the OKC, I believe they have a good chance, though I think they will be again underdog.
Updates, series tied with each team have 2 wins after Spurs loss on Game 4. The Spurs 3 point shots are nowhere to be found, Belinelli and Bertans were not a treat on Game 4. Derrick White, wasn't aggressive compared to previous 3 games.
Looks like the Nuggets wanted the game 4 more. Home court advantage now back to Denver.
The Nuggets - Spurs series will be a nice series that I predicted before starting the playoffs. I think this will go probably to 7 games now that the score is tied already. The Nuggets are strong but lack of experience in playoffs but the Spurs are have more experience in playoffs but probably weaker compare to the other team (personal opinion).
