It's always been a stupid concept anyway. This is what wins now. About time people realise it. 2011 Mavs and 2014 Spurs were largely jumpshooting teams as well. Even LeBron's Miami teams relied on floor spacing and Battier/Miller/Allen making 3's.
The new thing might be that teams that play 2 bigs don't win, or teams that don't can't score don't win. Memphis, Indiana, Chicago... Even the Spurs only won last year after ditching the big lineup. As did GS this year.
