I don't see any upsets in the East. Top 4 seeds advance to Round 2 and that's where things will get bloody, bad blood among those four teams that remain.
However, in the West...I can see the Spurs dismantling the Nuggets. Pop and the Spurs have been there too many times. The Nuggets have too much pressure with a #2 seed. Also, OKC Thunder is too dynamic for Trail Blazers to handle. Other than that, Warriors in 5, Rockets in 6. Now that Round 2 battle is gonna be good between GSW and Houston. I got Houston in 6 there- Warriors dynasty comes to an end.
