"Poll question: Have we seen a shift in the balance of power in the NBA?"
Of course its a very fluid situation pending some free-agent decisions.
After obviously GS, the next 4 best teams in the NBA are arguably:
Milwaukee Toronto Philly Boston
The rest of the West? Houston was a better team last year, they obviously fell off. Denver is good but young. This is basically the same Portland team that got swept in the first round by the Pelicans last year. This is obviously a down period for the Spurs. OKC was actually a threat until PG got injured. Utah and the Clippers are whatever.
As far is next year Kawhi could definitely shift the balance of power but the Bucks, sixers and Celtics are expected to be just as good if not better next year. If Oladipo comes back 100% the pacers appear ready to push into that top 4.
Out west the Warriors will still be good but may be weakened. Houston is expected to decline. Denver will probably be back and better and may challenge for conference supremacy. The Blazers pretty much are who they are. I don't foresee much of a change with the Spurs and Utah. Who knows with OKC.
