Styles are cyclical and are directly correlated to the type of player available at the time.
Teams trying to emulate what GSW are doing will fail miserably because those teams do not have Curry, Thompson and Green to build around. The trend to more perimete oriented basketball is simply because there are not enough dominant low post players in the league and there is an overflow of chucking guards so the trend has moved in that direction.
Are you saying that is by some miracle you could inject in prime SHAQ, olajuwon, Ewing, Mouring, Robinson, Duncan etc... into the current NBA that the trent would still be the same as it currently is?!
No chance in hell. It would be returning to low post, smash mouth basketball. I actually like the fact that Memphis has bucked the trend and are playing the style of basketball that suits their roster. You play to your player's strengths and not to a trend. As soon as another team other than GSW wins the championship, all of a sudden the trend will be very different and teams will try and copy those teams. It wasn't that long ago that the "big 3" teams were the tredny things to do. Now it's all about the Warriors. If SA wins this year's championship it will be about SA. There are multiple ways to get there. Smart coach coaches to his roster's strengths. There is no point turning DMC into a perimeter, running big when he is unguardable force down low. He needs to develop that low post game more but let's not fotget that there were games this season where DMC single handedly fouled out the other teams entire frontline when he was camping down on the block.
